Framing leaves no room for a linear slot plenum boot
Do not crush the boot to fit the framing. Verify the diffuser line, boot volume, framing conflict, and approved custom/narrow plenum option before finish work locks it in.
Do not hammer a plenum boot flat to force it into a tight finish opening.
Check
Measure actual framing gap against the diffuser/boot layout.
Check whether the boot is hitting track, drywall, ceiling wires, light fixture, or structure.
Do not modify factory diffuser/boot until foreman approves.
Sketch a revised boot shape that keeps internal volume and collar position.
Coordinate before drywall/finish ceiling is locked.

Say this to your foreman
The framing at [location] is too tight for the linear slot plenum boot. I checked the actual gap and collar path. Do you want a custom narrow/taller boot or framing coordination before drywall closes?
