What do I check for finish work: installing lay-in diffusers cleanly?

Lay-in diffusers must sit clean in the grid, line up visually, connect without stress, and remain serviceable for TAB and maintenance.

Stop if

• This diffuser sits crooked because the connection above is pulling it. Should I adjust the connection, hanger support, or wait for layout correction?

Watch out

• Stop if the device is carrying duct weight, the grid is being forced, or the connection blocks required balancing/access.

Check

• Set the diffuser square in the grid.
• Confirm the face is flush and not twisted.
• Connect the neck/boot/flex without crushing or sharp bends.
• Check damper handle/adjustment access if present.
• Clean the face before final walk.
