Content Container Models 1221-DOW and 1221-OW are "out of wall" high performance combination fire/smoke damper specifically designed for applications where the damper cannot be installed within the plane of the wall or floor. They features Nailor’s unique inter-locking double skin airfoil blade design that eliminates combustible seals and provides flame and smoke seal under fire conditions at temperatures up to 2000°F (1093°C)! Model 1221-DOW is designed for ducted through penetrations where as Model 1221-OW is designed for applications that terminate at a grille and provide easy actuator access.
