What do I do when not giving straight section off collar before bend?

Flex Duct Connections & SupportsPolished core starter — flex/manufacturer check

Give flex a short straight section off the collar before bending when space allows. Immediate bends can pinch the liner.

Field checklist

Ask foreman

This flex bends immediately off the collar. Do you want a straighter exit or hard duct extension?

Do not

Do not force an instant hard bend off the collar.

Why it matters

A sharp bend right at the collar is a common airflow killer.
