1Height over the bar
Measure the finished height at the spot where the rack will stand, not the room average. Ducts and beams often cross exactly where you want to lift. If they cannot move, the rack can.
Where the joists allow it, leaving that part of the ceiling open and painted gives you the depth of the joists back. Whether a ceiling can stay open depends on what the joists are made of and on your town’s code, and we check both.
