Stop if

Does this tight space clear the TDC/Ductmate flange, gasket, bolts, and insulation?

Watch out

Do not measure only the duct body when flange hardware must pass through the space.

Check

Check duct outside dimension plus flange.
Measure clearance at the tightest point.
Include gasket, bolts/clips, insulation, and access.
Verify adjacent trades/ceiling.
Ask before installing if the flange makes it too tight.
