3M 7000132507 Heat Shrinkable Cable Breakout Boot

Product Description

The 3M 7000132507 is a heat shrinkable cable breakout boot designed for dependable insulating and sealing of cable breakouts in multiconductor armored or sheathed cables and conduit ends. Sold as a single unit, this boot carries the model designation HDBB-405-1-250 and features a 4-way outlet configuration in black. It is constructed from flame retardant, cross-linked polyolefin and meets material requirements of MIL-I-81765-1. An internal adhesive coating is factory-applied to deliver reliable environmental sealing once the boot is shrunk into place. Electricians and low-voltage cable technicians working on shielded or armored cable assemblies rely on this type of boot to maintain system integrity at branch-out points.

This breakout boot is suited for use in both industrial and commercial electrical installations where multiconductor cables split into individual runs. Common applications include cable tray systems, conduit terminations, and armored cable assemblies where moisture ingress and mechanical stress at the breakout point must be controlled. The 4-way outlet geometry accommodates cable configurations that branch into four conductors or sub-cables from a single trunk.

Key Features

• Flame retardant, cross-linked polyolefin construction meets MIL-I-81765-1 material requirements
• Internal adhesive lining provides reliable environmental sealing after heat application
• 4-way outlet configuration for multiconductor cable breakout terminations
• Black color finish; model HDBB-405-1-250
• Provides electrical and mechanical protection at cable branch points
• Suitable for armored, sheathed, and conduit-end cable applications

Compatibility

Designed as an OEM-style heat shrink solution for multiconductor armored or sheathed cables and conduit ends requiring a 4-way breakout boot termination.

Installation Notes

Installation is typically performed by a licensed electrician or qualified cable technician. De-energize and lock out the circuit before handling any cable termination. Apply heat evenly using a calibrated heat gun, working from the center of the boot outward toward each outlet to ensure proper shrinkage and adhesive flow. Follow applicable NEC requirements for the cable type and installation environment.
