3M 7000133843 Fire Barrier Sixplex Mounting Brackets

Product Description

The 3M 7000133843 is a pair of sixplex mounting brackets designed for use with six 4-inch square 3M Fire Barrier Pass-Through Devices arranged in a 2 x 3 array. These brackets provide structural support when stacking six devices together, either vertically or horizontally, in multi-device firestop assemblies. Each pair includes the necessary bracketing screws and is designed to mount on both sides of the assembled unit. The brackets are compatible with pass-through devices that incorporate a fixed fire-rated intumescent material and a foam smoke seal, working together to create a listed firestop assembly in rated wall and floor penetrations.

These mounting brackets are used in commercial and institutional construction where multiple cable or pipe penetrations require firestop protection in a single location. Typical applications include data centers, hospitals, multi-family residential buildings, and other occupancies subject to fire-rated assembly requirements. They support larger cable management configurations by allowing square pass-through devices to be stacked in multi-device arrangements, consolidating firestop work at a single penetration point. Installation is performed by qualified firestop contractors or licensed electricians working to applicable building and fire codes.

Compatibility

Installation Notes

Installation should be performed by a qualified firestop contractor, licensed electrician, or other trade professional familiar with rated assembly requirements. Verify that the wall or floor assembly fire rating is appropriate for the intended penetration before beginning work. Follow all applicable building codes and the manufacturer's listed system instructions for the pass-through device assembly. Do not modify the bracket configuration in ways not specified in the listed system details, as doing so may compromise the firestop rating.
