Spring loaded double 'V' clamp centers the wire for the piercing needle, delivering reliable, consistent taps. Key features and benefits Insulated wire piercing without cutting or stripping insulation, saving time and preserving wire integrity. Pierces insulation on wires from 22 to 14 AWG (0.030 inch through 0.180 inch diameter), covering common small to medium sized wires. Tiny hole left in insulation can easily be sealed, allowing a reversible or resealable contact if needed. The spring loaded double 'V' clamp ensures the wire stays centered for accurate piercing and stable connection. How it works The spring loaded double 'V' clamp holds the wire centered for the piercing needle. It pierces insulation on wires within the 22 to 14 AWG range (0.0300.180 inch diameter). A small hole remains in the insulation and can be sealed after tapping. It makes contact with insulated wires without the need to cut or strip insulation. Applications and use scenarios Automotive wiring harness tapping: connect sensors or test equipment to 2214 AWG wires without removing insulation. Home electrical repairs: add a quick, nondestructive tap to existing insulated wiring without stripping insulation. Electronics prototyping and RC hobby projects: tap power or signal lines on insulated wires for rapid testing and experimentation. Compatibility and performance Suitable for wires in the 22 to 14 AWG range, corresponding to diameters of 0.030 to 0.180 inches. Designed to provide secure contact with insulated conductors while preserving insulation and wire integrity.
