3M 7000132576 Heat Shrinkable Cable Breakout Boot

Product Description

The 3M 7000132576 is a heat shrinkable cable breakout boot designed to insulate and seal cable breakouts in multiconductor armored or sheathed cables and conduit ends. Sold as a single unit, this boot carries the model designation HDBB-310-1-250 and features a 3-way outlet configuration in black. It is constructed from flame retardant, cross-linked polyolefin meeting the material requirements of MIL-I-81765-1. An internal adhesive coating provides reliable environmental sealing after shrink, making it suitable for both electrical and mechanical protection in demanding wiring applications.

This boot is used in installations where multiconductor cables must be properly terminated and protected at breakout points. Typical applications include armored cable systems, sheathed cable assemblies, and conduit entry points in industrial, commercial, and utility electrical work. The 3-way outlet design accommodates standard cable branching configurations. Electricians and electrical contractors working on medium- and high-voltage cable systems are the primary installers of this component.

Key Features

• Heat shrinkable construction provides a tight, conforming fit over cable breakouts
• Flame retardant, cross-linked polyolefin material meets MIL-I-81765-1 requirements
• Internal adhesive coating ensures reliable environmental and moisture sealing
• 3-way outlet configuration accommodates multiconductor cable branching
• Provides both electrical insulation and mechanical protection at termination points

Compatibility

Designed as an OEM-style fitting for use with multiconductor armored or sheathed cables and conduit ends requiring insulated and sealed breakout protection.

Installation Notes

Installation is performed by licensed electricians following applicable NEC guidelines. De-energize and lock out the circuit before fitting the boot over the cable breakout. Apply heat evenly using a calibrated heat gun, working from the center outward to activate the adhesive liner and achieve full shrink. Avoid open-flame heat sources, which can cause uneven shrink or damage the boot material.
