DFD, FD, and FSD Series Fire/Smoke Dampers
Designed for installation in horizontal, non-concrete fire-rated barriers, the DFD, FD, and FSD series of fire and combination fire/smoke dampers can simplify duct penetration protection.
Dampers can be specified for use in UL floor/ceiling design I503 assemblies made from steel studs and gypsum board. Barriers install quickly and increase the amount of usable space in the area.
