3M Fire Barrier RC-1 Restricting Collar

A Small but Vital Part of an Effective Firestop SystemWith its small but critical design features, 3M Fire Barrier RC-1 Restricting Collar is integral to successful intumescent firestop installation around penetrations in wall, floor and floor/ceiling assemblies. Quite simply, it’s a crucial component for ensuring that elastomeric and hard char firestop material will properly close openings left by burned non-metallic pipes and other penetrations. In fact, the use of such a collar is required for firestopping plastic pipes larger than 4 (101.6 mm) in diameter. The Fire Barrier RC-1 is ideal for use in conjunction with 3M Fire Barrier Wrap Strip FS-195+ or 3M Fire Barrier Ultra GS firestops.Recommended ApplicationsUL-classified for use on PVC, CPVC, ABS, CCPVC, CCABS, PVDF, PP and PB plastic pipeIn conjunction with 3M Fire Barrier Wrap Strip FS-195+In conjunction with 3M Fire Barrier Ultra GSThe Basis for Durable FirestopsDurable 28-gauge steel is thin enough for installers to easily unroll and cut to size around the installed firestop. It is quickly secured into place with a hose clamp or steel tie wire. Notches in its outer edge of the RC-1 Restricting Collar form bendable tabs – installers simply bend them into place and use hardware such as masonry fasteners (sold separately) to anchor them to the floor or ceiling slab. The result is a permanent, fixed firestop that also contributes to the structural stability of the penetration.The Science of Better Fire Protection from 3MSince 1925 when a lab assistant invented masking tape, 3M has been applying science to life –developing adhesive products and technologies that help entire industries and individual businesses worldwide. The work that began with a single 3M engineer now spans decades and generations. And all of it goes into each adhesive, sealant, and protective coating, along with the best ways to use them – including 3M Fire Barrier RC-1 Restricting Collar – to improve performance, and to help businesses like yours operate faster, better and more efficiently.
