Helps ensure secure installation of expandable firestop and proper closure during fire
Durable 28-gauge steel protects firestop material
Convenient roll is easily cut to size
Bendable tabs let installers anchor penetrations to slabs quickly and permanently
Use in conjunction with 3M™ Fire Barrier Wrap Strip FS-195+ or Ultra GS
Expands up to ten times its original volume, forming a very hard char to prevent the migration of fire and smoke
A Small but Vital Part of an Effective Firestop System With 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 Applications
UL-classified for use on PVC, CPVC, ABS, CCPVC, CCABS, PVDF, PP and PB plastic pipe
The Basis for Durable Firestops Durable 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 3M Since 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, 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.
