Used in conjunction with 3M™ Fire Barrier Pass-Through Devices.
3M™ Fire Barrier Pass-Through Devices use a unique fixed fire-rated intumescent material which works in conjunction with a foam smoke seal and optional mounting brackets. In the event of a fire, intumescent material quickly expands to seal the inside of the device, helping to prevent the spread of smoke and fire into other compartments. Optional mounting brackets and additional foam smoke seal replacements (device comes with 2 foam seals) sold separately.
