What do I do when flex restriction hidden above ceiling?
Airflow/TAB Impacts From InstallationV136 field-polished — distinct TAB/airflow answer
Hidden flex restrictions become hidden airflow complaints. Check the whole run before the ceiling closes.
Field checklist
- Run your hand/eyes from boot to collar.
- Look for kink, crushed liner, sag, tight strap, sharp bend, or excess length.
- Correct support and bend shape before cover.
- Photo the corrected run if asked.
- Ask before closing if the route cannot be made smooth.
Ask foreman
This flex restriction will be hidden after ceiling at [location]. Do you want it corrected before cover?
Do not
Do not leave hidden restrictions because nobody can see them from the floor.
Why it matters
Once ceiling closes, a simple flex fix becomes a callback or punch item.
