3M Fire Barrier Plastic Cast In Place Device, 4", 4PCID
This 3M™ Fire Barrier Cast-In Device 4PCID is an intumescent device that firestops 4 inch (101. 6 mm) non-metallic penetrations through fire-rated concrete floor assemblies. It is installed by attaching directly to the form before a concrete slab is poured. The 3M™ Fire Barrier Cast-In Device is installed prior to the concrete pour creating a firestop sleeve through which a four inch penetrant (e. g. non-metallic pipe) may be passed. It creates an opening through which mechanical, electrical or plumbing penetrants can be routed after the slab is cured and forms are removed. It is installed by attaching directly to the form before a concrete slab is poured. This device helps prevent the spread of fire, smoke and noxious gas through the penetration opening. 3M™ Fire Barrier Cast-In Devices can be used with the following accessories:3M™ Fire Barrier Cast-In Metal Deck Adapter to accommodate fluted metal decks, 3M™ Fire Barrier Cast-In Device Height Adapter to accommodate up to 12 inch (304. 8 mm) concrete thickness, 3M™ Fire Barrier Cast-In Aerator Adapter for aerator systems (use only with 4 inch 3M™ Fire Barrier Cast-In Devices), and 3M™ Fire Barrier Cast-In Tub Box Assembly to create a void for plumbing access (for use only with 2 inch metallic (50. 8 mm) 3M™ Fire Barrier Cast-In Devices).
