The Allproof Drop In Fire collars have been designed to and tested on wide range of plastic plumbing pipes. This is a simple and effective passive fire rating option for thin concrete floors or composite steel tray concrete floors. These floors feature profile changes on the underside of the slab and make it difficult to fire rate with a conventional fire collar fixed to the underside of a floor slab. The Drop In Fire collar allows the penetration to transition through at any location on the composite floor profile. Drop in fire collars are all installed from the top of the floor, making this an easier install compared to the conventional fire collar that is fixed from the underside of the floor.

The Drop In Fire Collars profile collars consist of an intumescent strip encased in a galvanised steel casing with extendable fixing tabs. The extendable tables allow for fixing the collar at the required height on different composite profiles and topping thicknesses.

In the event of a fire, the intumescent material expands against the steel casing as the penetration service melts or deforms. The fire collars steel casing is an excellent heat conductor, enabling fast activation of the intumescent, forming a stable fire-resistant seal, maintaining both fire integrity and insulation.

The Allproof Drop in fire collars have been tested at accredited fire laboratories in accordance AS1530.4 and AS4072.1. The Drop in Collars have been tested and designed for both stack and floor waste penetrations.
