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.
['Linear slot diffuser boots have to fit the architecture and still move air. If framing squeezes the plenum box, smashing the boot creates airflow restriction, noise, and ugly finish coordination.', 'Check the print, framing dimension, diffuser location, collar clearance, and plenum volume. The likely recovery is a revised narrow/asymmetric boot, trimmed flanges where allowed, a shifted framing member, or a custom taller plenum that preserves airflow without rattling against finish work.']
