The door closer is the device that is attached to the top of the door. With oil pressure, you can adjust the speed of opening and closing the door, and quietly close the door. Although it is a device commonly used in gates, it is also used indoors. It can also be used to prevent accidents in families with elderly and children, and it can be used flexibly.
The door closer will gradually deteriorate when the door is opened and closed. In Japan, where the temperature difference between the four seasons is large, the oil used in the door closers will age and the switching speed will change.
Once the oil leaks out, the door closer cannot be oiled. The door closer needs to be replaced because it cannot be disassembled or modified.
Especially in the case of no problem, it is recommended to carry out maintenance when using for about 10 years.
