3M Fire Barrier Cast-in Device for 4 in Metal Pipe

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.
