NSi Industries Easy-Twist wire connectors

The Easy-Twist WC-B-B-NL 1,000-Count Bag of Standard-Style Blue Wire Connectors are designed for use on copper wires in the 22-14 AWG size range. Theyre made of flame-retardant thermoplastic rated for a maximum temperature of 105 Celsius (221 Fahrenheit). The quick-grip square spring design grips in fewer twists and can dead-end a single wire, while the ergonomic 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.
