  • Radiation dampers are often required by code for multi-story residential buildings and help to prevent heat and flames from traveling through ductwork via a fire resistant curtain that automatically closes when excessive heat is detected. Sold as Project Packs only, requires purchase of housing and finish packs to complete the installation.

    • Kit includes metal grille, metal duct connector, hanger bars and plaster guard (housing not included) to give you a complete damper accessory kit for select fans
    • Fusible link holds curtain open until it senses 165 degrees heat, then breaks to release the curtain, effectively closing off the duct to help prevent heat or flames from spreading, keeping other areas in the building safer
    • 4-inch metal duct connector ensures heavy duty, long lasting operation and the ability to stand up in severe environments
    • Adjustable hanger bars span up to 24-inches to fit most applications and make retrofit easy
    • UL listed (standard 555C) for use in 1-, 2-, or 3-hour fire-rated floor-ceiling and roof-ceiling designs and for use in the following wood truss construction assemblies: L521, L528, L546, L558, L562, L574, L576, L581, L583, L585, P522, P533, P538, P545 and P547
