Allproof's Cast-In Fire Collars are designed to reduce the labour content of passive fire rating plumbing pipe penetrations on concrete floors that are poured on site. Simply fix the base to the formwork on site and the plumbing pipe penetration is complete with passive fire protection.

This process eliminates both the need for core drilling of penetrations after the floor is poured and retrofitting a fire collar or wrap. This method allows structural steel to be installed around the penetration. Once the floor is poured and formwork stripped, simply cut off the top of the Cast-In Fire Collar and install pipe.
