this section will not clear without rotating it before the threshold. Do you want it moved as-is, split, or brought in by another route?
Watch out
Do not bow, rack, or crush duct to make it pass through an opening without approval.
Check
Measure the tight opening, turn, ceiling height, and landing area.
Identify the duct's strong handling points and any vulnerable flange, reinforcement, liner, or coating.
Assign one person to call the movement and keep the path clear.
Use protection for finished surfaces and stop before forcing the piece into a bend it cannot make.

I measured the door and turn; this section will not clear without rotating it before the threshold. Do you want it moved as-is, split, or brought in by another route?
