Self-Adjusting Wire Stripper/Cutter

The Klein Tools Self-Adjusting Wire Stripper/Cutter handles stripping tasks for electricians and technicians working with residential and light commercial wiring. It automatically adjusts to strip 10 to 20 AWG solid wire, 12 to 22 AWG stranded wire, and 12/2 or 14/2 Romex cable. An integrated wire cutter in the handle adds cutting convenience without switching tools. Grooved grips are designed for added comfort during repetitive use.

Adjustable Stopper and Tension Control

An adjustable stopper sets the length of the core strip for consistent results across multiple wires. A tensioning thumb screw allows precise calibration for smaller gauge wire to prevent nicking or damaging the conductor. The self-adjusting mechanism removes the need to manually select settings for each wire size within the supported range. These controls give the user direct influence over strip quality for the listed wire types.

Upgrade from Fixed-Gauge Strippers

This tool replaces fixed-gauge strippers that only accommodate a single wire size or require manual jaw changes. The jump is worth it for professionals who regularly encounter mixed solid, stranded, and Romex wire in the 10 to 22 AWG range. It is not suited for users who primarily work with wire gauges outside the specified 10 to 20 AWG solid or 12 to 22 AWG stranded capacities.
