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

WireGard twist-on wire connectors are engineered for general-purpose electrical applications requiring reliable connection of two or more copper conductors. Each connector features a knurled thermoplastic shell for a secure hand grip and easy installation. The high-dielectric outer shell includes a deep skirt design to prevent bare wire exposure while providing flame retardant and chemical resistance. Inside the shell, a square-wire zinc-plated steel spring tightens around conductors as torque is applied, creating a continuous low-resistance electrical connection. Suitable for residential, commercial, and appliance applications, these color-coded twist-on connectors provide dependable wire splicing performance.
