Specifically designed for making positive ground connections with a hole in the tip of the connector to feed ground wire through. GreenGard connectors feature the same live-action as GB WingGard connectors with knurled wings for a sure grip and greater twisting leverage/torque. In addition GreenGard connectors offer added plating protection for corrosion resistance in grounding applications. Inside the connector a zinc-plated square wire spring ensures a secure connection that resists corrosion. The thermoplastic shell is designed for long-lasting strength and resists chemicals while the deep skirt supports smooth wire entry and coverage of stripped wires. Use for ground applications, building wire, lighting fixtures, luminaries and signs.
