The Intumescent Pipe Collar is a surface-mounted circular metal unit for use around pipes (PVC, UPVC, steel, and copper) and electrical cables that pass through fire-rated ceilings or walls. The unit consists of a hinged, two-part metal collar that contains intumescent material. It has a quick-release pin to open the unit for fitting around a pipe or cable, and fixing lugs are fitted for easy attachment to ceilings, floors, or walls. The collar can be reversed, to fit into the floor or wall. Standard finish in brown powder-coating (other colours available). These units are made to give from 1 hour to 4 hours of fire protection, and they are made in various sizes protecting pipes from 45mm external diameter (or narrower), right up to 600mm.
