Phantom of the Opera
i guess the motor is some sort of a mechanical stop, after all the spring is just to make it easier to open
I would think to ask the G Door company....I have worked on enough 'normal' 16-18' wide overhead doors to know they are HEAVY AS HELL, and when a 'normal' sping breaks, you can't open the door, if it's anything but just a thin metal shell, like mine with brace bars....all you can do to get a 2x4 on a fulcrum under the damn thing to lift it enough to do anything, if needed.....
I hesitate to rely on any mear opener for a safety stop....but I didn't design or do the install, just a word of caution so for the knowing....please do some investigation over it....maybe call the maker, see what they say....get it from horses' mouth.......I would not trust any mear installer on that one....:twitch::amazed:
