FR Collar - Technical Data Sheet

Protecta® FR Collars are designed to maintain the fire resistance of fire rated walls and floors where these are breached by service penetrations, and may be used in drywalls, masonry or concrete walls and floors. Each collar consists of a white coated circular steel shell that splits in two to fit around the service penetrations by means of a simple slidelock system. The steel shell contains a graphite based reactive material which reacts when exposed to heat from fire closing the openings left by the softening combustible material.
