Fireshield Pass-Thru 4" square

Bio Fireshield® Pass-Thru Devices are pre-firestopped and are designed to allow electrical, data or communication cables and pipes to penetrate fire-rated floors and walls. They consist of a square or round section steel sleeve which contains intumescent material. When exposed to heat, intumescent materials expand to form a insulating char plug which restricts the spread of flame, toxic gases, smoke and water. Each device is supplied with 2 end plugs which are inserted after the cable or pipe has been installed to reduce smoke leakage. The devices have an excellent "L" air leakage rating The devices can be opened for easy installation, retrofit or removal of cables. The devices are installed using specially designed mounting brackets which clamp onto the device and require no additional attachment to the wall or floor.

Bio Fireshield® Pass-Thru Devices are used to seal cables or pipes that penetrate thru 1 and 2 hour fire-rated walls and floors. Suitable for most types of construction including concrete floors, concrete walls, concrete block walls and gypsum drywall, and rated wooden floors. Individual devices can be assembled together to form double, triples and sixplex units using mounting brackets (purchased separately). Ideal for use in data, communications and electrical supply cables.
