  • Eliminates time and expense of drilling firestop holes in concrete
  • Designed specifically for metal pipes and other metallic through penetrants
  • 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.
  • Tear strips allow installers to easily adjust height for various concrete thicknesses
  • Installs securely by attaching directly to forms and floor decking
  • Rugged one-piece design withstands impact during everyday construction
  • Intumescent devices are firestop tested for up to 3 hours in accordance with ASTM E 814 (UL 1479)
  • Firestopping through concrete used to mean three things: pouring the concrete, core drilling holes, and firestopping later. Our 3M™ Fire Barrier Cast-In Devices eliminate the time and expense of firestopping metallic penetrants using extra materials such as pipe devices, strips and caulk. This allows for secure, permanent firestop installation before concrete is poured. A series of built-in tear strips makes for fast, easy height adjustment: using only a pliers, installers can quickly adjust the height in 1/2 inch increments from its maximum 8 inches (203.2 mm) to as low as 2-1/2 inches (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. Its black cap, easily visible after pour, signifies it as a pass-through device for metallic penetrants.
  • Our intumescent 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.
