3M 7000133835 Fire Barrier Metal Deck Adaptor 4 Inches

Product Description

The 3M 7000133835 is a metal deck adaptor designed for use with the 4-inch 3M Fire Barrier Cast-In Device. It allows the cast-in device to be mounted on fluted metal deck assemblies, a common structural configuration in commercial and multi-story construction. The adaptor requires a minimum concrete topping of 2.5 inches over the fluted deck to achieve proper installation depth and maintain the fire-rated assembly. It is sold as a single unit and is installed by fire-stop or mechanical contractors during the rough-in phase of construction. Weighing 0.58 pounds, it is a lightweight but purpose-built component within a listed firestop system.

This adaptor is used in commercial construction projects where concrete poured over fluted metal deck creates the floor-ceiling assembly. It is suited for through-penetration firestop applications where conduit or piping passes vertically through concrete-over-metal-deck floors. The adaptor accommodates both metallic and non-metallic models of the 3M Fire Barrier Cast-In Device, giving installers flexibility when specifying the primary device for the job. It is not a standalone firestop product and must be used as part of a listed system.
