Collars
Fire-stop collars (also called intumescent collars) are passive fire protection devices designed to restore the integrity of fire rated walls and floors when penetrated by pipes, conduits, or cables. They contain an intumescent material that expands under heat, sealing off openings and preventing the spread of smoke across assemblies.
