WireGard High Performance Twist-on Wire Connector, Red #18-#10 AWG 6/Card

Handle demanding multi-wire electrical splices and heavy-duty branch circuits with Gardner Bender WireGard Red Twist-On Wire Connectors. Designed for #18 through #10 AWG copper conductors, these high-performance wire nuts feature a straight polypropylene shell with deep knurling for a comfortable, non-slip grip that reaches full torque with fewer turns. The interior zinc-plated square-wire spring expands around the wire splice to deliver positive continuity, excellent corrosion resistance, and superior pull-out hold. Built with a flame-retardant thermoplastic housing rated up to 105°C (221°F), each connector includes an extended protective skirt to completely enclose stripped wire ends and prevent short circuits. Rated for up to 600V in building wire and 1000V in lighting/fixtures, this convenient carded 6-pack is UL listed and CSA certified.

Key Features:

• Heavy-Duty Wire Capacity (#18 to #10 AWG): Engineered for larger wire combinations and high-capacity residential/commercial circuits.

• Square-Wire Zinc Spring: Tight square-profile spring bites firmly into conductors for reliable electrical continuity and high pull-out resistance.

• Ergonomic Knurled Grip: Straight-sided ribs allow quick, slip-free tightening with less hand fatigue and fewer turns.

• Deep Dielectric Skirt: Fully conceals bare conductor ends to protect against electrical flashovers and short circuits.

• Flame-Retardant Construction: Resists heat distortion up to 105°C (221°F) and shields against chemical exposure from oils and mild solvents.

• Voltage Ratings: Rated up to 600V maximum in general building wire and up to 1000V in luminaires, signs, and fixtures.

• Compatibility: Copper-to-copper wire splices only (solid and stranded).
