Door Closer - a construction of mechanical nature, which is designed to automatically close open doors. The closer device provides for smoothly bringing the door to the “closed” position and ensures its tight pressing against the frame contour. However, in the modern market not only standard models of closers are presented. For example, there are devices that can lock the door in the “open” position. What is a door closer with latching in the open position? How to choose the right mechanism of this type. How can I install it myself? Look for answers to these questions in our material.
To begin with, it should be noted that closers are installed on those doors that are equipped with access control. Also, these devices are suitable for fire and evacuation floors. If we talk about mechanisms that have the function of fixing the door open, then it should be noted that such designs are most often used where it is necessary to ensure a large cross of people (for example, shops and boutiques, shopping centers and movie theaters, schools, universities and offices). If there is such an closer on the doors leading to the public premises, then the patency of visitors will be carried out without delays in opening and closing.
Equipped with a specialized design, the door can be opened only once, then it will maintain this position until the end of the day. In addition, such a latch for the door is useful to organizations and companies involved in trade, for example, shipping and unloading goods. It will help to solve a large number of problems and will allow you to enter or leave the premises, even if your hands are busy.
How to choose?
There are several mandatory characteristics and criteria that you should definitely pay attention to when choosing a door closer. So, when choosing and buying a device, you should consider the weight and width of the door leaf. Obviously, the wider, heavier and more massive the door, the more difficult it is to hold it, respectively, the more powerful the closer will be. Do not neglect this characteristic and do not rely on chance - the manufacturer carefully verifies the operation of the closer and the door parameters most suitable for it. Inattention to this criterion can lead not only to a breakdown of the closer itself, but also to disruption of the door.
An equally important indicator is the local climate and environmental conditions. It is important to understand in which temperature ranges the device will function. So, on the construction market special thermostable models are presented that can operate in a wide temperature range. Also, in order for the closer to function fully and correctly in case of unexpected and sudden temperature changes, it is recommended to purchase and install a special thermal shutter, which is a special device for internal valves.
When buying a mechanism, you must also carefully read the operating instructions. It is in it that you can find out all the necessary information about the manufacturer and make sure that you are purchasing really high-quality goods. Also, do not hesitate to ask the seller for a license and quality marks. The closer purchased by you must comply with the European standard EN 1154 or domestic GOST R.
How to install?
To easily install a do-it-yourself door closer that responds to opening a door, you must use one of four possible methods:
- installation in a frame;
- floor installation;
- door mounting.
Turning to the direct installation of the latch, which is able to hold the door in the open position, you should make sure that the rod is in the installation state. Then you need to check that the central screw is tightened tightly (if this is not the case, then tighten it using a six-sided wrench). The next step is to move the vertical relative to the horizontal shoulder until the shutter is blocked by a spring ball.
After that, it is necessary to unscrew the central screw 2 turns (so that the vertical shoulder moves regardless of the horizontal). Now it's time to establish traction with the closer. When this procedure is done - open the door to the angle in which it will be held by the closer in the open position and hold it. Tighten the center screw again.
The main part of the work is completed, the door is locked in the "open" position. Then unlock the door to check the operation of the closer (to do this, pull it). Next, the closer will close the door to the end. Thus, you and I were convinced that installing a door closer that is able to hold the door in the open position is a process that almost everyone can carry out. The main thing is to strictly follow the instructions. It is also important to choose the right design, and for this it is necessary to take into account all the advice of specialists and rely on the above instructions.
