The FR COLLAR is an intumescent collar composed of a circular steel housing that is divided in two to fit around the fire compartments by means of a simple “sliding lock” system. The steel casing contains a reactive graphite-based material that reacts when exposed to heat, closing the openings left by the installation’s combustible material.
The FR COLLAR is designed to maintain the fire resistance of fire-rated walls and floors where they are traversed by the fire compartments. They can be used on plaster, masonry or concrete walls and floors.
