What do I do when forgetting to measure finished wall thickness before duct sleeve?

Measuring, Field Verification & Layout MarksFoundation layout starter — field verify before cutting/loading

Measure finished wall thickness before laying out a duct sleeve. Rough framing and finished wall faces are not the same.

Open in Field Rescue Open category

Field checklist

Confirm wall type and finish thickness.
Check sleeve size/location/detail.
Account for fire/smoke/rated requirements if any.
Coordinate with other penetrations.
Ask before cutting or setting sleeve.

Ask foreman

What finished wall thickness and sleeve detail control this opening?

Do not

Do not size or locate a sleeve from unfinished wall assumptions.

Why it matters

A sleeve that fits rough framing can be wrong after finish layers are installed.
