3M™ Fire Barrier Pass-Through Products

Available from 3M Building and Commercial Services Division

The 3M™ Fire Barrier Cast-In Devices are a line of firestopping devices that are installed to firestop combustible and non-combustible pipe and cable penetrations through concrete floor assemblies.
The devices are installed before the concrete is poured and attached directly to the wood forms. Up to 3 hours of fire protection.

After the concrete cures a pipe is passed through the firestop cast-in device. There is no need for additional steps to firestop with caulk, wrap strip etc. It is one-step firestopping. The line consists of 2", 3", 4" and 6"diameter (8-inch tall) devices for both metallic and nonmetalic pipe penetrations up to three hours in concrete as thin as 2.5". There are also accessories for fluted deck applications and a height adaptor to accommodate pours up to 12".
