3M 7000133836 Fire Barrier Height Adapter 2 Inches

Product Description

The 3M 7000133836 is a height adapter designed for use with the 2-inch 3M Fire Barrier Cast-In Device. It extends the allowable concrete pour depth by 4 inches, supporting installations requiring up to 12 inches of pour depth. The adapter snaps onto the cast-in device, which is then secured to metal deck formwork before concrete is poured. It is installed by fire-stop or general contractors working on penetration firestop systems in concrete floor and ceiling assemblies.

This adapter is used in commercial and multi-family construction where fire-rated concrete floor assemblies require greater slab thickness than the base cast-in device accommodates. It fits both metallic and non-metallic versions of the 2-inch 3M Fire Barrier Cast-In Device, making it suitable for projects with mixed pipe or conduit material specifications. Typical applications include high-rise, healthcare, and other occupancies with code-mandated firestop assemblies at penetration points.
