3M 7000133837 Fire Barrier Height Adaptor 3 in

Product Description

The 3M 7000133837 is a height adaptor designed for use with 3-inch 3M Fire Barrier Cast-In Devices. It extends the allowable concrete pour depth by 4 inches, enabling installations in slabs up to 12 inches thick. This adaptor is used where standard Cast-In Device height is insufficient for deeper concrete pours, giving installers the clearance needed to meet project specifications. Licensed fire-stop and construction contractors install this component during concrete formwork or pre-pour preparation on commercial and residential projects requiring through-slab penetration firestop systems.

This height adaptor fits installations where concrete slab thickness exceeds the standard device range and a full 12-inch pour depth is required. It accommodates both metallic and non-metallic versions of the 3M Fire Barrier Cast-In Device, making it a single SKU solution for mixed-penetration projects. Typical applications include multi-story commercial construction, concrete floor decks, and any project where deep slab pours are specified by structural or fire-rated assembly drawings.

Key Features

• Extends allowable concrete pour depth by 4 inches over the standard Cast-In Device height
• Supports pour depths up to 12 inches (304.8 mm)
• Compatible with both metallic and non-metallic 3M Fire Barrier Cast-In Device models
• Designed for 3-inch Cast-In Device configurations
• Lightweight at 0.43 pounds for easy handling during formwork installation

Compatibility

Designed for use with 3-inch metallic and non-metallic models of the 3M Fire Barrier Cast-In Device in concrete slab firestop assemblies.

Installation Notes

Installation is typically performed by a licensed fire-stop contractor or journeyman electrician prior to concrete pour. The adaptor must be secured to the Cast-In Device and positioned correctly within the formwork before concrete is placed. Verify that the assembly meets the applicable UL fire-rated assembly requirements and local building code before pouring. Do not alter, cut, or modify the adaptor, as doing so may void the fire-rated listing.
