Nondestructive insulation piercing: Make contact with insulated wires without cutting or stripping insulation. Precise, centered piercing: Spring loaded double V clamp holds the wire centered for the piercing needle, improving reliability and reducing the risk of misalignment. Wide wire compatibility: Pierces insulation on wires from 22 to 14 AWG (0.030 inch through 0.180 inch diameter). Small, sealable hole: The insulation hole is tiny and can be sealed easily after tapping. Practical and timesaving: Enables fast electrical taps without removing insulation or rewiring, preserving wire harness integrity. Use scenarios: Automotive wiring taps to add a sensor, indicator, or accessory without cutting wires. Quick diagnostics or test leads in control panels or equipment with tight spaces. Prototyping or modifying electronic projects where preserving insulation and harness integrity matters. Key attributes: Function: Insulation piercing contact without stripping or cutting. Compatibility: Works on wires 22–14 AWG (0.030'–0.180' diameter). Mechanism: Springloaded double V clamp centers the wire for accurate piercing. Performance: Leaves a tiny hole that can be sealed easily, enabling reliable connections in compact wiring environments.
