{"product_id":"3m-fire-barrier-rc-1-restricting-collar-mmm-rc1-2","title":"3M Fire Barrier RC-1 Restricting Collar","description":"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.","brand":"3M Canada","offers":[{"title":"Default Title","offer_id":42871280959577,"sku":"MMM-RC1-2","price":0.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0601\/1171\/6441\/files\/MMM-RC1-2_1_20-_20bfab6f6f-21a3-48d3-a8f5-57499f6acd22.jpg?v=1764098786","url":"https:\/\/www.guillevin.com\/products\/3m-fire-barrier-rc-1-restricting-collar-mmm-rc1-2","provider":"Guillevin","version":"1.0","type":"link"}
