Before choosing a door closer, you should consider: door weight, door width, door opening frequency, use requirements and use environment.


Door weight and door width are the premise of choosing the model of the door closer. Generally, the door weight is small and the model with small power is selected. First, it is very easy to open the door, and it is installed on the door.


Coordinating aesthetics; second, small products are generally more economical, and vice versa.
