The ROKU® FSC 4 system consists of an all-metal cuff that is fitted with multiple layers of ROKU® Strip EM intumescent material.
In the event of a fire, the intumescent material expands and seals the opening from fire and smoke. For wall mounting, one pipe clamp should be provided on each side of the wall, and for floor mounting, one clamp should be provided on the underside of the floor.
Sealing plastic pipes max. Ø up to 160 mm in solid walls, plasterboard partitions and hard floors.
