What do I do when not verifying sleeve/breakaway connection requirements?

Fire/Smoke Dampers, Access Doors & Rated AssembliesHigh-risk starter answer — manufacturer/project/code/AHJ verification required

Breakaway connections, sleeves, and retaining angles are listed damper-installation details. Do not invent them or swap them with a normal duct connection.

Field checklist

Read the manufacturer/submittal detail for sleeve, angles, fasteners, and breakaway connection.
Confirm which side(s) require breakaway and what connection is approved.
Ask before fastening, sealing, or modifying the damper connection.

Ask foreman

The damper instructions call for breakaway connections. Can you show me the approved detail before I connect this?

Do not

Do not treat damper or rated-assembly work like normal duct. Do not substitute normal duct connection habits for a damper installation detail.

Why it matters

A breakaway connection lets duct release under fire/thermal movement so the damper stays in the rated wall. It is not a normal field preference.
