I’m installing metal on my ceiling and am now installing where the overhead door tracks are. I have two doors, the main one is a 20’ wide by 14’ tall heavy insulated door. The smaller is 12’x12’. They were installed by an overhead door company a couple years ago and I’m just now doing the ceiling. The inside of the vertical door tracks are exactly 246-1/2” bottom, middle, and top of the vertical. The horizontal tracks are where I have questions. They installed the rear of the horizontal tracks 1” narrower than at the front where it meets up with the vertical tracks. When the door is up, I can see where it’s bulging the horizontal track outwards. When I called them asking about this, they were absolutely no help. Only thing he would say is “reinstall them exactly the way they were”. My question now is, is it normal to narrow up the horizontal tracks at the rear, or should I make them the same 246-1/2” apart as the vertical are. I can square them up by measuring diagonally, if I end up changing the width.
