Insulation-Piercing Wire Taps





Connect a tap wire to a main wire without stripping—these wire taps penetrate insulation. To install, squeeze the tap with standard pliers; a built-in U-shaped metal contact penetrates the insulation and grips the wire.
UL 94 V-2 or V-0 rated taps meet flammability standards.

Twist-On Insulation-Piercing Wire Taps


Convenient for jobs where you don't have crimpers on hand, these wire taps twist together to connect a tap wire to a main wire. The cap locks the wire into place, making them good for high-vibration applications. As you twist the cap onto the main wire, it pierces the insulation, so you don’t need to strip the wire. However, you’ll need to strip the tap wire.
