The 3M Fire Barrier Plastic Pipe Device is a one piece metal collar assembly encasing 3M's heat-expanding 3M Fire Barrier Ultra GS material. Used to firestop up to nominal 6" diameter non-metallic pipes, cables and combos in new and retrofit installations. Achieves up to 3-hour fire protection in tested and listed systems.A Quick Fit for Durable Firestop Protection Incorporates our 3M Fire Barrier Wrap Strip FS-195+ and is specifically designed to be a firestop for non-metalic, 6” pipe penetrations. This one-piece metal collar is built to fit securely around the firestop wrap strips – no additional assembly is required. Tested for up to 2 hours of fire protection in tested and listed systems, the device holds firestop material in place and helps ensure proper closure during fire. Metal tabs make for fast, easy anchoring to wall or floor slabs with common tools and hardware such as toggle bolts for gypsum or masonry anchors for concrete. (Hardware sold separately.) The result is a permanent, fixed firestop that also contributes to the structural stability of the penetration. Recommended Applications • For installing firestop around 6" non-metallic pipe in new and retrofit through penetration installations • In conjunction with 3M Fire Barrier Wrap Strip FS-195+ The Science of Better Fire Protection from 3M Since 1925 when one of our lab assistants invented masking tape, 3M has been applying science to life –developing adhesive products and technologies that help entire industries and individual businesses worldwide.
