JOINTS – AF Multi Collar Pro+ 3m

AF MULTICOLLAR PRO is a modular fire-rated pipe collar suitable for insulated metal pipes, electrical conduit pipes, multilayer pipes, and plastic pipes.
In the event of a fire, the collar’s graphite-based structure expands against the surrounding construction, sealing the opening left by the melted pipe and forming a tight firestop.
It prevents the spread of flames, hazardous smoke, and heat through floor and wall structures.
The fire collar provides up to EI 120 / EI 180 fire resistance in walls and floors.
