Sleeve/breakaway connection requirements not verified

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

Stop if

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

Watch out

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

Check

• 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.
