I'm looking at the belt drive system. Mentions Posilock system to keep it closed. By what mechanism does that work? How high security is it?
This system actually secures 95% of all doors in America today. It is one of the most secure methods of locking your door. As the opener closes the door about 2' before it closes the draw bar goes from pushing horizontal to pushing down vertical. When the door stops it is pushing the door down to the floor. In order to break in to the door you would need to sheer 2 2" lag bolts out of the header. This is very secure. This negates the need for an inside slide lock or an outside keyed entry. Thanks BB
