3M 7000133834 Fire Barrier Metal Deck Adaptor 2 Inches

Product Description

The 3M 7000133834 is a metal deck adaptor designed for use with the 3M Fire Barrier Cast-In Device in 2-inch configurations. It allows the cast-in device to be mounted on fluted metal deck assemblies, a common structural substrate in commercial and light-industrial construction. Installation requires a minimum concrete topping of 2.5 inches over the fluted deck profile. The adaptor accommodates both metallic and non-metallic versions of the 3M Fire Barrier Cast-In Device, making it a versatile component for firestop rough-in work on metal deck floors and ceilings.

This adaptor is used in commercial construction and renovation projects where fluted metal deck is the primary floor or ceiling substrate. It is installed during the rough-in phase before concrete is poured, positioning the cast-in device correctly for post-pour access. Firestop contractors, general contractors, and journeyman installers working on multi-story commercial buildings will encounter this application when sealing penetrations through concrete-over-metal-deck assemblies.

Compatibility

Compatible with the 2-inch 3M Fire Barrier Cast-In Device in both metallic and non-metallic configurations, for use on fluted metal deck assemblies with a minimum 2.5-inch concrete topping.

Installation Notes

This adaptor is installed by firestop or general contractors during the pre-pour rough-in phase on metal deck floor assemblies. Confirm the concrete topping will meet the 2.5-inch minimum depth before positioning the device. Follow the project engineer's firestop submittal and applicable building and fire codes for penetration sealing requirements. Do not install the cast-in device without the adaptor when working over fluted metal deck, as improper seating can compromise the rated assembly.
