QUESTION: I have auto repair dealer with roll up door h.10feet wide 12 feet should i use lift master 3950 or mj5011u oh the shaft is 11/4 in? by bich t 9/29/2016
ANSWER: We are a car dealer also, have the 3950 mounted on one of our 4 doors. It is by far better than the track and chain systems on the other doors. Our doors are the same size as yours. Only advice is to buy the bumpers for the top, so it puts preload on the door cables when the door is fully open. If you dont you run the risk of the cables unwinding, thats not fun. by joe h a
STAFF ANSWER: Hello,<br />Either one would work I would probably stick with the 3950 by Taylor M a
