Wire piercing probe for quick, reliable electrical access on insulated wires Why you need this Make electrical testing and diagnostics faster and neater by piercing wire insulation without stripping the conductor. Compatible with common automotive and household wiring, so you can get an accurate signal or measurement with minimal wire damage. Compact, lightweight, and supplied as a pair for convenience during multipoint checks or for keeping a spare. Key benefits Fast access: Designed to pierce insulation on wires from 14 AWG to 22 AWG, 0.03 inch through 0.18 inch diameter, so you can tap into a wide range of wire sizes without cutting. Clean and repeatable contact: The probe creates a small puncture that allows reliable electrical contact while leaving the wire usable. Portable and easy to store: Small plastic body and low weight make these probes easy to carry in a toolbox or service kit. Two per pack: Includes 2 wire piercing clips so you can test two points at once or keep a backup.
