The 3M™ Fire Barrier Plastic Pipe Device UPPD4 is a one-piece metal collar assembly encasing 3M's heat-expanding 3M™ Fire Barrier Wrap Strip Ultra GS Material. The 3M™ Fire Barrier Plastic Pipe can be used to firestop up to four inches (101.6 mm) of non-metallic pipe, cables and combos in new and retrofit installations. It achieves up to 3 hours of fire protection in tested and listed systems. This device also mounts easily and quickly (takes about 1 minute) when using 3M™ Ultra Fast Anchors and Pliers (requires 3 anchors, anchors sold separately), no power tools, mounting screws or other fasteners needed. It can also be anchored using conventional methods (e.g. toggle bolts for gypsum or masonry anchors for concrete).
