QUESTION: Can the 3900 be mounted in the center of the torsion bar? by Mike D 9/2/2016
ANSWER: I don't think so because I believe the door would run right into it. The unit will hang down approx 18 inches that's why I believe it would have to be mounted on the side of torsion. It's designed to slide over the end of the rod on either side of door. Hope this helps . by fred P a

REPLY: Looking at my door as it comes up there is only approx 4" of clearance between torsion bar and door and the open hangs approx 12" below the bar and sticks out 7". With that being said I'm not sure the clearance you have. I'm not sure if anybody has ever tried to flip the unit upside down that way it would only stick down approx 3" ? Just a thought ... by fred P r
