3M™ Fire Barrier Cast-In Tub Box Assemblies eliminate the time and expense of firestopping metallic penetrants using extra materials such as pipe devices, intumescent wrap strips and caulk, allowing for secure, permanent firestop installation before slabs are poured. Firestopping through concrete used to mean three things: pouring the concrete, core drilling holes, and firestopping later. This device removes some of that time and labor. The device secures easily to floor decking, and its one-piece design withstands the everyday impact and wear of the construction site.
