What do I check for finish work: transfer grilles and return air path?

Finish Work, Punch List & CloseoutVerified starter — finish work field check

Transfer and return devices support airflow paths. Finish install needs to match the designed air path, not just cover a hole.

Open in Field Rescue Open category

Field checklist

Match grille size and type to schedule.
Check opening alignment from both sides if paired grilles are used.
Keep path clear of insulation, packaging, debris, or blocked plenum.
Do not add or enlarge openings in rated assemblies without direction.
Confirm final face is clean and secure.

Ask foreman

Is this transfer/return opening in a rated wall or controlled assembly, and do we have the correct grille/detail before install?

Do not

Stop if the wall is rated, smoke-controlled, fire-rated, or if the return/transfer path is not shown clearly on approved documents.

Why it matters

Finish work is where rough-in becomes visible, inspected, balanced, serviced, and turned over. Clean install and access matter.
