Apex door closer does not close the door. What is door closer setting

Today's technologies make life much easier. For example, such a device as a door closer eliminates the need to constantly check whether the front door of the entrance is closed. Today, manufacturers produce several types of such a device, which are installed on entrance doors or interior doors. Pretty handy, easy to set up and adjust.

In order to pick yourself required model closers, it is worth considering what types are, and for what doors they are intended. The closer model should be selected taking into account the parameters of the door, namely the width and weight of the door leaf. You should also consider the temperature range at which the door closer will have to work.

The main types of automatic closer mechanisms:

1. Top overhead closers are mounted on the wall and firmly held on top. They provide smooth closing of the door. Mechanisms with a gear drive or a sliding rod are produced. The cost of such a mechanism is relatively low. Such closers are very easy to install.
2. Floor closers are much more expensive than the first type and require special installation conditions. Most often, they are used for a door that opens in both directions. Also, such a mechanism is very convenient to install on glass and intercom doors.
3. Concealed door closers are designed for installation directly in door leaf and a box. To install this type of closer, you will need a door with a thickness of at least 40 mm. They are almost invisible. Installation of this type of door closer is quite complicated and requires special knowledge and skills.

The street closer is equipped with a mechanism that is lubricated with a special liquid to increase the resistance to high temperatures. In other words, if you install a closure designed for use during indoor areas on the access door, its performance will deteriorate significantly, and the service life will be greatly reduced.

What is a door closer and how does it work?

In its work, the door closer is similar to the spring mechanism, which was previously installed on doors and gates. But the disadvantage of such a device was that the door slammed very loudly and closed abruptly. With the advent of modern devices for automatic closing doors, the problem with the formation of noise has gone into oblivion.

The principle of operation of a door closer is very simple.

The main working part of this device is a spring and an oil shock absorber, which is responsible for the smooth closing of the door. Through a special valve system, the oily liquid, depending on the direction, flows from one chamber to another during operation.

Peculiarities:

1. The movement of oil is hydraulic system regulated channels.
2. The oil in the mechanism has a rather viscous consistency, due to which the opening and closing process runs smoothly and silently.
3. The force and speed with which the mechanism works depends on the type of device.

Parameters are easily adjusted using special adjusting screws. The tighter the screws are clamped, the slower the fluid flows through the channels. You can remove and adjust the door closer with your own hands, having carefully studied the principle of operation of the mechanism.

Installation and adjustment of the door closer

Basically, door closers are designed for installation on front doors. During installation, the body of the closer is positioned so that it is in the room, it is impossible to remove it from the outside. This arrangement of the case provides additional protection of the mechanism from moisture, dust and dirt.

To install a door closer, you will need:

• Drill;
• Ruler;
• Simple soft pencil;
• Screwdriver.

Mounting materials are included with the mechanism. For ease of installation, most manufacturers complete the device with installation templates that show all parts of the door closer in full size. Also on these templates you can see the places where it is necessary to make holes for fasteners. Using a template, holes are made in the intended mounting location of the closer. Then proceed to the installation of the device itself. The body is attached first, which subsequently must be connected to the thrust lever. If you follow the instructions, the installation of the door closer will not take much time.

As a rule, closers have different design and the location of the adjustment screws. Adjustment of the closer is carried out according to the same scheme, regardless of the design of the device - by turning the screws clockwise, the speed and strength of the closer increases, or by turning the screw counterclockwise, it means slow closing of the door.

Most often, to tighten the screw, it is enough to make a quarter turn. If you upset the balance and strongly tighten or unscrew the screw, you can completely upset the operation of the mechanism, which is then difficult to restore. Incorrect adjustment may damage the device.

Instructions: how to adjust the door closer after installation

After installing the closer, its adjustment is necessary for the optimal rate of closing the input or street door. It is necessary to adjust the door opening speed with the help of screws, which are located on the front side of the case under a special protective cover.

This function is especially useful when installing the door closer on interior door.

Slow closing will avoid damage to the walls. There are several additional functions that help to set the optimal closing and opening of the door.

Locks with electromagnetic or electromechanical action:

• Are established on entrance doors;
• Where is the intercom located?
• On the door, which restricts the access of strangers to the entrance.

Such a mechanism closes the door to the end and opens only with a special key. Door closers with delay function are necessary in in public places to facilitate access to the premises for people with handicapped. Most often, the delay is set to 30-40 seconds. Adjustment of the argument is applied when closing the door at the last stage. This function makes it easier to click the lock and helps to avoid the rapid escape of heat from the room.

Adjustment of the door closer during operation

If it becomes necessary to personally adjust the pace of closing and opening the door, you need to pay attention to the basic rules and nuances of the process. Each device comes with detailed instructions which will help to implement this process right.

Basic adjustment steps:

• The first screw must be turned half a turn counterclockwise to adjust the reach;
• The second quarter-turn screw clockwise speeds up the opening;
• The third screw, which is located on the side of the case, regulates the force of movement.

It is very important to remember that in order to weaken or increase the pace, the screws must not be unscrewed more than 2 turns. This action will cause oil to leak out. It is impossible to repair the door closer at home. For this reason, adjustments must be made carefully, following all directions in the manufacturer's instructions.

Quite often, the closer needs additional adjustment. If the closer works hard, and when you open the door, you need to make an effort - then you need to loosen the screws, and the door will work softly. Sometimes it becomes necessary for the door to be constantly open, loosening the screw completely will help with this.

The screw keeps the door open for as long as necessary.

The screws can be located on the side or on the front side, it all depends on the mechanism. You can find out the location of the screws by looking at the instructions, where the manufacturer indicates the location of all parts and parts of the closer. To date, several models of closers are in great demand, which are easy to operate, install and adjust.

Experts have created a list of the most popular models:

1. Dorma– closers are suitable for installation on metal doors outdoor and indoor use.
2. Bulat frost-resistant, made of durable metal alloy.
3. Diplomat It is made of high-strength steel, which allows it to withstand sudden temperature changes.
4. Apecs have an additional function of permanent fixation.

All of these models have a lot of advantages, thanks to which they are becoming more and more popular every day. Most manufacturers, in the manufacture of door closers, use only quality materials which increase the service life of the product even under the heaviest loads.

Do-it-yourself door closer adjustment (video)

Summing up, we can safely say that closers are useful and convenient fixture. They are easy to install and operate. All models are equipped with special bolts, which regulate the speed and force of retraction or closing of the door. Additional functions of the door closer allow you to keep the doors in the open or closed position. It is necessary to purchase closers from official representatives who can sell according to OKVED.

The door closer is a necessary and useful invention. This is a mechanism that automatically closes the doors and contributes to less wear and tear. door hinges and accessories. Properly performed installation and timely adjustment of the door closer will guarantee its Good work and long service life.

Device features

Almost all door closers, regardless of the manufacturer, have the following functions:

1. Sliding speed of the door leaf.
2. Closing smoothness.
3. The ability to keep the door open.

The sliding speed of the door leaf can be faster or slower. It is regulated by the degree of tension of the spring inside the device. It must be remembered that in no case should you pull the door, helping the closer. This will quickly disable him.

Dokhlop allows you to smoothly close the door, suspending the canvas just before closing itself. This function ensures silent operation of the door, eliminating loud noises. In addition, the door flap contributes to a tighter fit of the door leaf to the frame. The angle at which it will slow down before fully closing is usually in the range of 10-15 degrees. It can be adjusted when adjusting the closer.

Sometimes it becomes necessary to leave the door in the open position. A function called "hold open" helps with this. Thanks to her, the sash can remain open long time. When the door is fully opened, a latch is activated in the device, which will hold the canvas in this position. To close the door, you just need to pull it slightly towards you. The lock will release and it will close smoothly. If the door is not fully opened, it will operate normally.

How to adjust for each individual function is described below.

When to Adjust

Adjustment of the closer must be carried out when the seasons change. Because it mechanical device, then for him correct operation oil is used, which changes its physical characteristics depending on air temperature. With its increase in viscosity working fluid decreases, and as the temperature drops, the oil thickens. Therefore, in the first case, the door will open too easily, and in the second, significant efforts will be required. Therefore, in spring and autumn, you need to adjust the operation of the door closer mechanism.

In addition, the adjustment of the door closer is carried out in the event that there are problems in closing the door. They can be expressed as follows:

• too fast or slow closing;
• the door moves abruptly or with jerks;
• the canvas is not attracted to the frame for a long time.

How to adjust the closer correctly

Adjusting the door closer comes down to setting the operation of the valves inside the device, which act as a thermal damper. With their help, with changes in external temperature, the degree of increase or decrease in oil viscosity is compensated.

Adjusting the work is not difficult. All you need is a screwdriver and knowledge of the setup process. Before proceeding with it, visual inspection doors and check their operation. This is necessary to identify violations in the work and their subsequent correction.

Adjustment is made with screws. In some device models, they are hidden under a protective cover that needs to be pushed back. In others, they are not hidden by anything and are located on the side of the device panel. For ease of adjustment, the screws are numbered 1 and 2. The first affects the overall closing speed, the second affects the strength of the cotton.

DIY adjustment instructions

The closing speed of the sash is changed by screw number one. Turning counterclockwise speeds it up. By turning the screw clockwise, the movement of the sash slows down.

The strength of the pop is the range in which the door begins to slow down before fully closing. If there is a problem with the catch, then you need to turn screw number two. By turning it clockwise, you can slow down the speed of the clap. Turning the screw in the other direction, counterclockwise, on the contrary, will increase its strength.

To set the function that holds the door open, you need to fully open it, and then tighten the special lock. After that, the door will remain open if you open it at an angle corresponding to a given degree.

When adjusting the closer, follow the instructions given in the accompanying instructions for the device. Always remember that in order to avoid damage to the device, do not turn the screws more than two turns from zero.

Periodically inspecting the door closer and adjusting it if necessary with your own hands, you will extend the life of the device and ensure comfort when using the door.

Is it possible to manage Everyday life without door closers?

Of course. It's not hard at all to open and close behind you.

True, if the hands are busy, then it already delivers some inconvenience. And if there is a spring, then it’s quite a disaster.

Sometimes, a passing push in the back is comparable to the acceleration of free fall.

Therefore, setting up a door closer, even a spring one, is a rather relevant thing.

Of course, setting up this very closer will not be difficult.

The task of these devices is to close behind incoming and outgoing people.

Moreover, to do this according to a certain algorithm:

• Do not interfere with easy and free opening
• Do not close, at a certain opening angle
• Close at an adjusted, comfortable speed
• At the end of your movement - slowly, without knocking, clap, with a certain effort

A similar algorithm should be performed for doors of any design and purpose. There are a lot of designs and operating conditions of doors:

• outdoor
• Internal
• Interroom
• Swing
• metal
• Rights
• Left

Each door has its own weight

When choosing a specific model of the closing mechanism, all of the above options must be considered. This is especially true for the weight of the door leaf and temperature conditions.

In addition, the closers themselves are available in several modifications:

• With slide cam type mechanism.
• It has a smooth glide, but is used only for light canvases.
• With gear-lever mechanism. In this case, the movement of the door leaf is transmitted by a system of levers and a rack and pinion mechanism. The gear rack, performing reciprocating movements, plays the role of a rod distilling oil through adjustable jets.
• Outdoor execution. A similar mechanism is built into the floor when it is laid. Not widely used.
• Concealed installation. The working mechanism is built into the body of the door leaf.
• Overhead type. The most widely used type of door closer. Used for canvases different weight. When temperature conditions change, it needs to be adjusted.

When choosing a closer for a particular door, it is necessary to strictly compare its weight and performance with technical capabilities device.

Why is adjustment needed?

It is easy to imagine the work of a poorly adjusted closing mechanism.

If we take 2 extreme cases of poor adjustment, we get the following.

In the first of them, the closer will work like a strongly tightened spring.

People will have a hard time getting past it.

To top it off, the door leaf will knock with force on its box.

In order to correct the situation without adjusting the device, it will be necessary to hold it.

In the second case, it simply will not close or close only partially.

This is how the Diplomat door closer is configured. Its adjusting screws are located on the end surface of the device. Adjusting this screw changes the speed of the web in the range of 15 0 - 180 0 .

Such adjustments must be made with extreme caution. A fully turned out adjusting screw will inevitably cause system depressurization and oil leakage. The closer will be completely disabled.

Dohlop installation

Adjusting the door closing speed must be carried out regularly - at least 2 times a year. This is also necessary for purely preventive purposes, as well as in connection with a possible change in the physico-chemical oils.

At low temperatures it becomes sticky. At high values- becomes excessively liquid. In the first case, the door does not close well. The second is too fast.

The same arguments are relevant for such a function of closers as a close. This is especially important for doors with soft seals, magnetic or combination locks.

For such doors, the last moment of closing is very important. This range is in the range from 0 0 to 15 0 . In this range, the leaf must close slowly and securely.

Situations with increased dynamics or incomplete closure are unacceptable.

To adjust the door closer "Bulat" or close to it in design - "Diplomat", for these purposes a screw for adjusting the catch is provided.

Due to its rotation, the characteristics of movement will change in the range from 15 0 .

The screws for adjusting the speed and rebound are located side by side on the end panel of the device.

This butt is directed towards the door hinges.

As in the case of the speed adjustment screw, the rebound screw requires the same care when manipulating it.

Adjustment of the catch-up should be carried out only after the debugging of the speed characteristics is completed. Turning the adjusting screw clockwise decreases the speed.

Turning against it - makes the speed more. To avoid technical problems, do not make more than 2 turns in this direction.

Operating rules

These rules are simple and very clear. Devices designed to close doors are of low cost and are not equipped with various anti-vandal devices.

In this regard, they must be handled with care and rather delicately. Having chosen a closer, you need to make sure that its characteristics correspond to the conditions where they want to put it:

• Since closers are divided into classes from small - EN1 to large - EN7, then it is worth choosing them in accordance with them. It should be noted that these classes are associated not simply with mass, but with inertial mass. In other words, not only weight matters, but also the dimensions (shoulder) of the canvas. An appliance rated at 40 kg (EN1) cannot close a metal door weighing 120 kg (EN7).
• Don't help him with his work.
• It is not necessary to keep the sash open if the mechanism does not have such a function.
• There is no need to thoughtlessly turn the valve adjusting screws.
• Coordinate with the seller of the equipment the issue of setting it up with the left or right opening.

A beautiful door, a functional door closer, a bit of luck in adjusting it, and a bit of luck in life. Here working formula happy person. This article is one of the components of this formula. And luck is always there.

The video shows the installation of a door closer:

The closer allows the door to close smoothly and without shock. Due to this, the service life of both the door leaf and the locks is increased. Due to the fact that the door closer is constantly subjected to heavy loads, in order to ensure normal and reliable operation the mechanism must be carefully and regularly looked after. It is enough to make the necessary adjustments and the device will work flawlessly for many years. There are several options for regulation, you can do all the settings yourself, you just need to know how to do it right.

When is door closer adjustment needed?

The modern door closer appeared relatively recently. Its task is to ensure smooth closing of the door leaf. Such devices can be installed both on entrance and interior doors in houses and apartments, and in offices, shops, entrances, etc. Previously, a spring was used to close the door, but at the same time the canvas slammed shut with a thud and a blow occurred, which led to a quick failure of both locks and door leaf.

If earlier springs were used to close the door, now - modern devices called closers

The presence of a door closer on the doors suggests that when opening them, it will be necessary to apply a certain force, which accumulates in the mechanism located inside such a device. When closing the canvas, the door closer smoothly returns the door to its original position.

Before proceeding with the description of the process of adjusting closers, it is necessary to briefly familiarize yourself with their types. On sale you can find mechanisms of the following types:

• spring. This is the simplest model, which works by compressing the spring when the door is opened, after which it unclenches and the canvas closes;

  The spring closer is simple in design, as it works by compressing the spring

• cam with sliding (slide) traction. His work is based on the smooth sliding of the slide thrust. This mechanism is usually used for light weight door panels, as well as where such indicators as compactness, smooth running and small size closer;

  The cam closer has a sliding (slide) traction

• gear driven closer. This is the most common option. His work is based on the movement of the door under the action of gears. The toothed closer is more durable, so it can be installed on heavy doors.

  The operation of the gear closer is ensured by the gears present in it.

In addition, it is necessary to determine the types of door closer according to the installation method:

• overhead. These are the most simple models that are attached to the top of the door. They are usually mounted on the front doors to a house or apartment. It is easy to adjust overhead closers; for this, there are special screws on the mechanism body;

  The overhead door closer is attached to the top of the door

• floor. These models also have simple design, but their installation is carried out on the floor. In houses and apartments, floor models are practically not used. They are mainly installed in offices, shops and other institutions with high attendance;

  The floor closer is fixed on the floor

• hidden. Such structures are difficult both to mount and to regulate. This is due to the fact that they are either inside the door or in the floor, so getting to them is difficult.

  A hidden closer is hidden in the door leaf, frame or in the floor

In what cases it is necessary to adjust the closer

The door closer is operated in intensive mode, therefore, to ensure it normal operation It is recommended to carry out adjustment work at least twice a year. If the attendance of the premises is large, then the adjustment may need to be carried out more often.

Since there is oil inside most closers, adjustments must be made in the warm and cold seasons. This is due to the fact that when the temperature changes, the density of the oil also changes and the smooth operation of the device will depend on this.

There is oil inside most closers, its density depends on temperature, so adjustments must be made in the warm and cold seasons

It is necessary to constantly monitor the operation of the mechanism. If you are not satisfied with the speed of closing the door or it happens with jerks, and the canvas is not attracted well, to eliminate such shortcomings, it is necessary to adjust the closer.

Is adjustment required after installation of the device

Depending on the design of the closer, the location of the adjusting screws will differ. Despite this, the adjustment is carried out according to the same scheme - when the screws are rotated clockwise, the speed and force of the mechanism increase and vice versa.

Since the weight of the door leaf on which the closer is mounted can be different, adjustment should be carried out immediately after installation. Turn the screws very slowly. It is recommended to do no more than ¼ turn, after which it is necessary to check the operation of the closer. If the screw is loosened more than 2 turns, it may fall out of the socket, and this will lead to oil leakage.

Since the weight of the door can be different, it is necessary to adjust the door closer immediately after its installation.

Immediately after the installation of the door closer, they check its performance and if something does not suit them, they make adjustments. The speed at which the door leaf will close is changed by turning the corresponding screw. If you need to adjust the catch, use another screw.

Door closer adjustment

Now that you know the types of closers and decide which one is installed on a particular door, you can start adjusting it.

Although there are several types of closers, the principle of adjustment will be almost the same. Regardless of whether an overhead, floor or hidden mechanism is installed, you first need to study the instructions and determine how many adjustments this model has. The simplest mechanisms have only two adjusting screws located on the body of the device: one is responsible for the closing speed of the web, and the second for its closing. After that, the necessary function of such a device is adjusted. The process of adjusting hidden structures will be more difficult, but here you can do it yourself. It is enough to figure out where the adjusting screws are and use them to adjust required indicators closer.

To perform the work you will need the following tools:

Before proceeding directly to the adjustment, it is necessary to determine what the following terms mean:

Door speed control

The first step in adjusting the door closer is to set the closing speed. It is recommended to set a high door closing speed on the entrance doors so as not to lose heat; for interior doors, this figure depends on the preferences of the owners.

A door closer, depending on its model, can have from 2 to 5 adjusting screws, their purpose should be found in the instructions for the purchased device.

To adjust the door speed:

Throttle adjustment

The closing speed can only be adjusted after the door closing speed has been set. To adjust this parameter, you must use the second screw, which is on all door closer models:

Open position control

If you often need to fix the door in the open position, you need to buy models with an adjustment called hold open. This function is used when it is necessary to bring in or take out large items from the room:

How to loosen a door closer

If the doors are difficult to open, loosen the door closer. To do this, loosen the adjusting screws a little and ensure that a little effort is required to open the door leaf.

To loosen the closer, you need to unscrew the adjusting screws a little.

Setting the closing delay

Sometimes there are situations when it is necessary that the doors close not immediately, but with some delay. This feature is also not available on all models. To understand if it is on your door closer, you need to look at the number of adjusting screws. There should be more than two of them, and the purpose of each of them can be found by studying the instructions. This function allows you to configure the door closer so that several people can pass at the same time while the door is open. It is especially relevant in hospitals, shops, educational institutions.

Setting the door closing delay:

Video: closer adjustment

During self adjustment door closer, you must adhere to the basic rule: you cannot unscrew the adjusting screws by more than 2 turns. Almost all mechanisms run on oil, and if you unscrew the screws more, it will begin to flow out. Oil is poured into the device under pressure, so you won’t be able to fill the closer yourself and you will have to buy a new mechanism.

To provide maximum term closer service, you need to fulfill certain requirements:

If you really need to fix the door, and the closer does not know how to do this, some craftsmen disconnect the lever rods and turn off the closer in this way completely. To implement this method of fixation requires a certain amount of time and effort. To do this, use a screwdriver or wrench to unscrew and pull out the screw connecting the two lever rods. If the need to fix the door leaf occurs frequently, it is better to purchase a door closer with the appropriate function.

The door closer is pretty simple mechanism, and if it is properly operated and adjusted in time, then it will work for a long time and reliably.

With the development of technology, human life has become much easier. With such a simple device as a door closer, you will forget about the need to double-check if the doors are closed. Today, devices are available in several types and are represented by products from different manufacturers, differ in belonging to different price categories. We will figure out how to mount the door closer and adjust the door closer, how long this process will take and how difficult it is.

The main types of mechanisms and their internal structure

To choose a closer option for a door, you first need to understand the types of mechanisms and their designated purpose. The choice should be based on the parameters of the door, namely? width and weight of the structure. In addition, please note temperature regime the premises where the installation and operation of the element is planned.

The main options for auto-closers include:

1. Top overhead, which are mounted on the wall and firmly fixed on top of the door. The mechanism ensures smooth closing and a snug fit of the door. They produce two types of product models: with a gear drive or a sliding rod. Mechanisms of this category differ not high cost and belong to the category of available goods. In addition, they are easy and quick to install.
2. Floor closers. These products, in comparison with the previous considered option, are distinguished by a high cost. In addition, they require special installation conditions. Most often, such mechanisms are used for doors that open in both directions. It is convenient to install such a closer option for an intercom door or a glass structure.
3. Hidden closers. The products are intended for installation directly into the door leaf or frame. They are installed on doors with a thickness of at least 40 mm, becoming almost invisible. Installation is complex, requires special knowledge and skills.

Peculiarity street closer for the door - equipped with a special mechanism, lubricated with a liquid that increases resistance to high temperatures. That is, if you install such a closer designed for interior doors or used in installation on entrance doors with inside, outside, then its performance will deteriorate significantly, and the service life will decrease.

The principle of operation of the door closer

This device is similar in its work to the spring mechanism, which was previously installed on gates and doors. The disadvantage of such a device was far from smooth closing, and sometimes pops of the closing structure. As soon as modern automated systems, providing a smooth door movement, the problem with the formation of noise was solved by itself.

The main working part of the closer is a spring and an oil shock absorber, which is responsible for a smooth ride. The oily liquid circulating inside special valves flows from one chamber to another.

Features of mechanisms

To the number distinctive characteristics closers include:

1. Oil circulation occurs through a hydraulic system, adjustable valves.
2. Smoothness and noiselessness at opening/closing of a door is provided thanks to a viscous consistence of oil.
3. Depending on the type of device, the strength and speed of the mechanism may vary.

It is easy to adjust the parameters of the closer with the help of special adjusting screws. The tighter they are clamped, the slower the fluid flows inside the cylinder. Having carefully read the principle of operation of the mechanism, it becomes clear that it is not so difficult to remove and adjust the door closer.

How to mount and configure the door closer yourself

The main purpose of closers is to smoothly close the front door. When installing, make sure that the body of the product is on the inside of the room, which makes it impossible to dismantle the product from the outside. It contributes additional protection mechanism from the penetration of moisture, dust, dirt.

Mounting tools

During the installation you will need:

1. Drill.
2. Ruler.
3. A simple pencil with a soft lead.
4. Screwdriver.

There is no need to buy fasteners separately, they are included in the delivery of the door closer.

What does the installation process look like?

Some of the manufacturers add installation templates to the product kit with life-size images of all parts of the mechanism and the intended locations of holes and fasteners.

Having studied the template and the details of the installation of the mechanism, they proceed directly to the process of installing the device. First, the body is fixed, which, at the second stage, is connected to the traction lever of the structure. Following the instructions, you will see that the installation technology is not difficult and takes very little time.

Please note that the closers are structurally different, the location of the adjusting screws also varies.

Features of adjusting the door closer

The adjustment is carried out according to the same scheme, regardless of the design of the closer. By turning the screws clockwise, the speed of the mechanism and its strength is increased or, by rotating the screw in reverse side, means slower closing of the door.

When working with this design, try to turn the screws slowly and carefully - this is one of the recommendations of experts.

To tighten the screw, it is enough to make a quarter turn. By knocking off the balance and strongly tightening or unscrewing the screw, you run the risk of completely upsetting the operation of the mechanism, which as a result will be problematic to restore.

Incorrect adjustment of the door closer leads to its breakdown. This is worth paying attention to.

How to properly adjust the door closer after installation

This procedure is carried out in order to obtain the optimal rate of closing the front or street door. Adjusting the opening speed, as mentioned above, is carried out using screws located on the front side of the case and hidden under a special protective cover, which is especially good when installing the mechanism on an interior door. So the design looks more aesthetically pleasing.

By setting the system for slow closing, the owner will be able to avoid damage to the walls, and the presence of additional functions for adjusting the door closer plastic door opening will allow you to customize optimal mode device operation.

Features of self-closing devices

Where to install this kind of clamps:

• on the entrance door;
• where the intercom is located;
• on structures that restrict the access of outsiders to the entrance;
• on other door structures of the entrance and interior type, if necessary.

Thanks to this mechanism, the door closes completely, and opens only when using a special key. The door closer with delay function is an indispensable device for door structures in public places, facilitating access to the interior of the premises for people with disabilities. This feature allows you to set a delay of 30-40 seconds.

Closer adjustment for entrance doors carried out at the last stage, when closing the doors. Thanks to this function, it is easier to snap the lock into place and contributes to less heat loss when entering and leaving the room.

Features of the regulation of the door closer during operation

Sometimes it is necessary to make adjustments during the operation of the door, while it is worth paying attention to a number of rules and recommendations that greatly facilitate the task. Please note that each device is accompanied by detailed instructions that help simplify the process and control its correctness. After all, the master can always double-check the correctness of his actions by re-reading the points of the insert again.

A concise instruction for adjusting the closer is as follows:

1. During operation of the door, the first screw is turned half a turn counterclockwise, thereby adjusting the reach.
2. The second is a quarter turn clockwise, which helps to speed up the opening.
3. The third, located on the side of the body, is used to regulate the force of movement.

Remember simple instructions for adjusting the door closer with your own hands. To weaken or increase the pace, it is not recommended to unscrew the screws more than two turns. This can cause oil to leak out of the system, and repairing the structure at home is unrealistic. For this reason, the procedure is performed with extreme care, strictly following the instructions attached to the product by the manufacturer.

The need to adjust the door closer of iron and other types arises quite often. If the system works hard, and when opening the door, you have to make specific efforts in order to get in or out of the room, then the screws must be loosened to ensure smooth door movement.
