(3) When the door is too heavy or open the door when the force is too large lead to break the bar, the actual width of the installation when the width of the applicable door width. Due to the spring force can not reach the width should be installed after two or three months there will be no buffer phenomenon
3. Closed door will be stuck in a position can not move

(4) due to the production of bearing position is not built when the end will lead to the spring guide head is not in the middle, so the installation of two facade is not the same level.
