Choose A Suitable Door Closer To Consider The Width Of The Door

The swing doors in our lives generally rotate with hinges as the axis. The wider the door leaf, the greater the distance between the center of gravity and the hinge axis, and the greater the force required to control the rotation of the door. When we choose the door closer, we must first consider the width of the following door. If you choose a door closer with too small force level, the door cannot be completely closed due to the closing torque of the door closer when closing the door; if you choose a door closer with too large force level, it is convenient to close the door with sufficient torque when closing the door. Close the door, but it also brings other problems, such as being caught and knocked down by the door, and it takes a lot of effort to open the door when opening the door. In the EN standard, there is a corresponding relationship between the strength level and the width of the door leaf. We can choose the corresponding door closer according to the actual door width.
