Finger Sleeves (Breakout Boots)

Product Overview

Finger sleeves, also known as breakout boots, are multi-finger heat shrink sleeves for the cable branching point of three-core and four-core cables. On recovery, each finger separates and insulates an individual core where the cable divides, restoring insulation and core separation at the breakout.

They are made from crosslinked polyolefin with an optional adhesive lining, and are used in our three-core and four-core termination kits. The sleeves are also supplied as standalone items for cable accessory assemblers, panel builders and utility maintenance teams, manufactured from the same materials as our complete kits to ensure compatibility and consistent performance.

Applications

Cable Accessory Assemblers

Purchase finger sleeves in bulk for assembly into your own brand termination kits.

Panel Builder Components

Use finger sleeves in switchgear and panel assembly for cable preparation at breakout points.

Utility Maintenance Stock

Stock individual sleeves so field crews can replace parts of termination kits without replacing the entire kit.

FAQ

How do I choose the right finger sleeve?
Selection depends on your core count (three or four), core insulation diameter and voltage class. Send us these details and our engineering team will match the correct sleeve and provide dimensional drawings.
Should I choose the adhesive-lined version?
The adhesive lining is optional. It adds a sealing layer at the breakout point, which suits outdoor or damp locations; the plain version is available for dry indoor assemblies.
Can I order finger sleeves in bulk for my own kits?
Yes. Sleeves are supplied as standalone items for cable accessory assemblers, and OEM and private label supply is available on request.
What about minimum order quantity and lead time?
Tell us the component name, voltage class and quantity you need. Our engineering team replies with specifications, pricing and lead time within one business day.
