FlameSafe® Firestop Device
Creates an instant cold seal against fire, smoke and toxic gases on plastic pipes and non-metallic conduits. The FlameSafe® Firestop Device (FSD), available in several sizes, is a simple solution to PVC, CPVC and non-metallic conduit installations. Manufactured from a durable galvanized steel outer shell that is lined with highly intumescent, malleable fill material, it easily wraps around a pipe to produce an immediate cold gas fire seal. The device, also called a “collar,” bolts together and is affixed by screws to the wall or underside of a floor.
