The door closer is installed on the door. Its function is to automatically close the door when the door is opened. Its characteristic is that it can accurately close the door to the initial position. Door closers are widely used in our lives. It is mainly used in commercial and public buildings, but also in domestic use. Its biggest function is to close the door tightly when a fire occurs, thereby preventing the spread of the fire. In this issue, let's take a look at the installation and precautions of the door closer.
1. Five installation methods of door closers
There are five installation methods for door closers. Depending on the door, the installation method is different.
1. Standard installation:
The door closer body is installed on the side of the sliding door, and the support arm is installed on the door frame. This installation method is suitable for the narrow door frame and there is not enough space to install the door closer. This installation method is also suitable for opening the door to a large enough angle when there is no obstacle in the direction of the door, and the door closer will not hit foreign objects.
2. Upper door frame installation:
The door closer is installed on the side of the sliding door, and the arm is installed on the door. This installation method is suitable for a wide door frame with enough space to install the door closer. Compared with the standard installation, this installation method is suitable for obstacles such as walls in the direction of the door. Compared with the standard installation, this type of installation has a higher closing force and is suitable for larger and heavier doors.
3. Parallel installation:
The door closer is installed on the side of the sliding door, and the parallel plate is installed on the door frame. This installation method is suitable for the door frame is very narrow, or there is almost no door frame. After you install it in this way, because there is no protruding connecting rod and rocker arm, it is more beautiful. Compared with the standard installation, this installation is suitable for obstacles such as walls in the direction of the door.
Compared with a standard installation, parallel installation is suitable for small closing forces, and there are obstacles such as walls in the opening direction.
4. Hidden installation:
This installation method is the same as the slide rail installation for the concealed door closer. After being installed in this way, the door has no exposed parts in the closed state, so it is the most beautiful. This is the most complicated installation method, and it is best to require a professional to install it. This installation method requires a large gap between the door frame, generally 10MM (or remove the material on the upper part of the door during installation to increase the gap). The thickness of the door exceeds 42MM.
5. Slide rail installation:
Compared with the previous methods, it mainly installs the equipment on the door, and the slide rail is on the door frame, which is suitable for use in places with small closing force, and because there is no prominent connecting rod and rocker arm, it has a high aesthetics.
