3M™ Fire Barrier Cast-In Devices for Metal Pipes provide one-step firestopping for penetrations through fire-rated concrete floor assemblies. Instead of drilling holes, installers simply attach the devices directly to floor decking, pour slabs around them and route penetrants after curing. Heights are easily adjustable, and these intumescent devices are rated for up to 3-hour fire protection.

Simply a Better Way to FirestopFirestopping through concrete used to mean three things: pouring the concrete, drilling core holes, and firestopping later. 3M™ Fire Barrier Cast-In Devices for Metal Pipes eliminate the time and expense of firestopping metallic penetrants using extra materials such as pipe devices, strips and caulk, allowing for secure, permanent firestop installation before slabs are poured. A series of built-in tear strips makes for fast, easy height adjustment: using only a pliers, installers can quickly adjust the height of the device from its maximum 8” (203.2 mm) to as low as 2-1/2" (57.2 mm). The device secures easily to floor decking, and its one-piece design withstands the everyday impact and wear of the construction site even at floor level. Its black cap, easily visible after pouring, signifies it as a pass-through device for metallic penetrants.Recommended Applications Firestopping of metal pipes – copper, steel, iron, flexible gas For concrete thicknesses from 2-1/2” to 8” or higher in conjunction with 3M™ Fire Barrier Cast-In Devices Height Adaptor In conjunction with 3M™ Fire Barrier Cast-In Device Metal Deck Adaptor for attaching to fluted decksFully Tested and ApprovedIntumescent 3M™ Fire Barrier Cast-In Devices for Metal Pipes are firestop tested up to 3 hours in accordance with ASTM E 814 (UL 1479). They are UL Classified for 2- and 3-hour fire (F) rating, and 1- and 3-hour temperature (T) rating. They also meet UL Water Leakage Test, W Rating - Class 1 requirements for systems tested and listed in accordance with ANSI/UL 1479 (see system details).The Science of Better Fire Protection from 3MSince 1925 when a 3M 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 3M adhesive, sealant, protective coating and device including 3M™ Fire Barrier Cast-In Devices for Metal Pipes to improve performance, and to help businesses like yours operate faster, better and more efficiently.
