What This Helps With

If a damper, VAV, sensor, valve, cleanout, or service point is above a hard ceiling, access must be coordinated before cover.

Apprentice words: ceiling access panel, hidden damper, access above hard ceiling, VAV access, damper access panel

Common problem: Device is technically installed but impossible to reach once ceiling closes.

Check First

Device type, required access size/location, ceiling type, ceiling trade coordination, and labels on the ceiling/access panel.

What Not To Do

Do not cover life-safety/service devices without approved access. Do not assume ceiling contractor will add panels later.

What can go wrong: Device is technically installed but impossible to reach once ceiling closes.

Better Foreman Question

This device will be above hard ceiling. What access panel size/location is required before we cover?
