The Easy-Twist WWC-GR-C 100-Count Carton of Green Winged Wire Connectors are designed for grounding copper wires in the 14-12 AWG size range. They have a hole in the top designed for a through-wire and are made of flame-retardant thermoplastic. The quick-grip square spring design grips in fewer twists and can dead-end a single wire, while the ergonomic swept-back wing design and ribbed texture makes them easy to twist. Their compact design is useful for applications in tight areas or anywhere else you need to connect wires. Manufacture Part Number: WWC-GR-C UPC - 662381361653 Sold as a pack of 100 Units.
