3M 7000148880 Fire Barrier Metal Deck Adaptor

Product Description

The 3M 7000148880 is a metal deck adaptor designed for use with the 6-inch 3M Fire Barrier Cast-In Device. It allows the cast-in device to be mounted on fluted metal deck assemblies, which require a minimum concrete topping of 4.5 inches. The adaptor accommodates both metallic and non-metallic models of the 3M Fire Barrier Cast-In Device, making it a versatile component in fire-rated floor-ceiling assembly work. Licensed fire protection contractors and commercial electricians typically specify this adaptor during new construction on steel-framed structures with composite deck systems.

This adaptor is intended for commercial and industrial construction applications where fire-rated penetration sealing is required through fluted metal deck floors. It is used during the rough-in phase, before concrete is poured, to position the cast-in device correctly within the deck profile. The minimum 4.5-inch concrete topping requirement must be confirmed during the planning stage to ensure compliance with the fire-rated assembly design.

Key Features

• Compatible with 6-inch 3M Fire Barrier Cast-In Device models
• Designed for installation on fluted metal deck assemblies
• Accommodates both metallic and non-metallic cast-in device models
• Requires a minimum 4.5-inch concrete topping over the metal deck

Compatibility

Designed for use with the 6-inch 3M Fire Barrier Cast-In Device in both metallic and non-metallic configurations. Suitable for fluted metal deck floor assemblies with a minimum 4.5-inch concrete topping.

Installation Notes

Installation is typically performed by licensed fire protection contractors or commercial electricians during the pre-pour phase of construction. Confirm the concrete topping depth meets the 4.5-inch minimum before positioning the adaptor. Follow the applicable fire-rated assembly design documentation and local building code requirements. Do not install in assemblies that do not meet the specified concrete topping thickness, as this will affect the fire rating.
