Installation is easy! Everything worked well! The door was closed and the zuverlessig several weeks without any problems. This is a normal door. Until this morning when you open the door, a loud bang was heard. The plastic cap with which the spring is fixed, flew around the room. I have even secured the top two screws on the door leaf, I do not want vorstelllen me what would have happened if I niccht hhätte made. At once I have broken down the shutter. I think that something like this can not be sold.
