No cutting or stripping required: This tool makes contact with insulated wires without removing insulation, saving time and reducing wire handling. Precise insulation piercing: A springloaded double 'V' clamp centers the wire for piercing by the needle, ensuring accurate contact without damaging surrounding insulation. Clear sealing after use: The small hole left in the insulation can be easily sealed, helping maintain insulation integrity and moisture resistance. Wide wire compatibility: Pierces insulation on wires from 22 to 14 AWG, corresponding to 0.030 inch through 0.180 inch diameter. visible and identifiable: Bright yellow body for easy locating in work environments, with red or black colorcoded caps to assist quick circuit or polarity identification. Practical use scenarios: Automotive diagnostics: Tap into power or signal lines in automotive harnesses without cutting wires, enabling quick testing and temporary connections. Appliance service and : Access control or power circuits inside appliances without disassembly or insulation removal. Electrical panels and control wiring in field service: Make fast, nondestructive connections to lowvoltage circuits for testing or temporary leads while keeping insulation intact.
