Gardner Bender WireGard GB-4 Yellow Twist-On Wire Connector

Gardner Bender WireGard twist-on wire connectors are engineered for general-purpose electrical applications requiring the connection of two or more copper wires. Built with a tough thermoplastic polypropylene shell featuring side knurling, these connectors provide an easy grip and dependable insulation. The high-dielectric shell includes a deep skirt design to prevent exposure of bare wire and offers flame-retardant properties to resist heat distortion. Inside, a zinc-plated square-wire spring instantly adjusts to the shape and size of the conductor splice, ensuring positive continuity and quick, secure contact. These twist-on connectors require fewer turns to achieve required torque and meet or exceed UL pull-out and dielectric test requirements while resisting environmental extremes and chemical exposure.
