without stripping insulation. Snap the housing shut and the tin-plated blade pierces both insulations to create a reliable electrical joint.
Rated 600 V, 105 °C.
- No-strip, one-hand snap-on installation improves service speed.
- Nylon housing with corrosion-resistant, tin-plated piercing blade.
- Color-coded sizes cover 22–10 AWG (0.5–6 mm²).
