ProVent Systems’ ProSet embedded firestop coupling can control drain-waste-vent-pipe expansion and contraction problems in multistory buildings when it is anchored into a concrete floor or restrained using a special riser clamp. It has a complete line of systems for piping penetrations, encompassing all of the major construction systems and types of pipe. The penetrators can be used in a variety of other non-fire rated applications. The EZ Mechanical Flex coupling also can accommodate any movement of DWV pipe between two floors through the flexibility of its 3” and 4” sizes. The incorporation of Trap Guard allows users to specify an emergency or specialty drain system wherever there is a need, without worrying about the requirement for a trap primer or venting. All of these penetrations incorporate integrated fire stopping, smoke proofing, and waterproofing.
