The characteristic of the door closer is to accurately close back to the original position after the door is opened. It is widely used in our lives, mainly used in commercial, public buildings and home. The role is to close the door tightly in the event of a fire, thereby preventing the spread of fire.
Therefore, we should also learn to install and use door closer correctly. The following are several installation methods of door closer:
There are five ways to install door closer. Depending on the door, the choice of installation method is also 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 narrow door frames and there is not enough space to install the door closer. This installation method is also suitable for no obstacles in the opening direction, and when the door is opened to a large enough angle, the door closer will not hit foreign objects.
2. 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 wider door frames and enough space to install the door closer. Compared with standard installation, this installation method is suitable for obstacles such as walls in the opening direction. Compared with the standard installation, the closing force of this installation method is larger, which 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 very narrow door frames or almost no door frames. After installation, since 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 door opening direction. Compared with standard installation, parallel installation is suitable for low closing force, 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 hidden door closer. After installing in this way, the door has no exposed parts in the closed state, so it is the most beautiful. This installation method is the most complicated, and it is best to require professionals to install it. This installation method requires a large gap between the door frame and the door frame, generally 10MM (or remove the material on the upper part of the door during installation to increase the gap).
5. Slide rail installation
Compared with the previous methods, it is mainly to install the equipment on the door, and the sliding rail is on the door frame, which is suitable for places with low door closing force, and because there is no prominent connecting rod and rocker arm, the aesthetics is higher.
