I have a metal building that I am putting a metal ceiling in. I have 10 inches from the top of the rool up door to the bottom of the truss. Minus 2 inches for the ceiling metal, 4 for the door opener, that is liberal measurements. That leaves 4 inches for door clearance. Will quick turn top brackets I see listed give me enough clearance or is there other solutions. 2 track? Need help.
