The Lloyd 55CRD08 is a round ceiling radiation damper designed to protect ceiling openings in fire-rated floor and ceiling assemblies. It is rated for fire resistance of 3 hours or less and has been tested and labeled by UL. HVAC installers and contractors use ceiling radiation dampers wherever ductwork or air distribution openings pass through a fire-rated ceiling. The damper helps maintain the integrity of the fire-rated assembly by closing off the opening in the event of a fire. This is a code-required component in many commercial and residential construction projects where recessed lighting, diffusers, or duct openings penetrate rated ceilings. The 55CRD08 is a round unit sized at 8 inches in diameter, making it compatible with standard 8-inch round duct connections. It is constructed from 26-gauge galvanized steel, which provides corrosion resistance and durability in typical ceiling plenum environments. The unit is not insulated and carries no R-value rating, making it straightforward to specify when insulation is not required. It is not flanged. The damper measures 8 inches in length and width, with a height of 2.5 inches, and has a cubic measurement of 0.0926. It weighs approximately 2.05 pounds. Manufactured in the USA, the 55CRD08 meets Prop 65 requirements and is sold individually. This product is commonly specified by mechanical contractors, HVAC technicians, and building inspectors who require UL-listed ceiling radiation dampers for compliance with fire and life safety codes. It fits into standard ceiling grid and drywall ceiling assemblies where round duct penetrations are present.
