Rectangular Fire Damper 5-3/4x9-3/4 In

The Dayton rectangular fire damper fits 10-inch by 6-inch nominal ductwork and installs vertically or horizontally. It is intended for low-pressure HVAC systems that require a dynamic barrier rated for one and a half hours of fire exposure.

Capacity and headroom

The damper provides a free area of 0.219 square feet and uses a 165-degree fusible link to close automatically during a fire. Its 22-gauge galvanised steel construction meets UL 555, NFPA 80, 90A, 101, IBC, CSFM and NYC MEA standards, but the fire resistance rating is less than three hours.

Fusible link temperature

The 165-degree Fahrenheit fusible link determines when the damper activates, making it suitable only for environments where that trip point matches the design requirements. Systems needing a higher or lower activation temperature will require a different link.

Questions about this item

Will this 5-3/4x9-3/4 inch fire damper fit my existing 10x6 inch ductwork?

Yes. The damper is designed for a nominal duct width of 10 inches and a nominal duct height of 6 inches, matching your duct dimensions exactly.

How can I verify the 165-degree fusible link is functioning after installation?

The fusible link is a passive thermal device rated to release at 165 degrees F. It cannot be tested without destruction; visual inspection confirming the link is intact and correctly seated is the standard post-installation check.

Does the box include the 2TGG6 retaining angles needed for mounting?

The specifications list the 2TGG6 retaining angle as a recommended accessory. It is not included with the damper and must be purchased separately for proper installation.
