What is a breakaway connection on a fire damper?

Fire/Smoke Dampers, Access Doors & Rated Assembliesfield-polished — audit route

A breakaway connection is a listed duct-to-damper connection designed to release under fire/thermal movement so the damper stays in the rated wall. Use the approved damper instructions/submittal.

Field checklist

Find the manufacturer/submittal detail.
Confirm sleeve, retaining angles, fasteners, and breakaway method.
Ask before fastening, sealing, or modifying the 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 use a normal duct connection or whatever hardware is nearby if breakaway is required.

Why it matters

Breakaway is part of the damper listing/assembly, not a field preference.
