Connecting wires is faster and easier than ever with the professional performance features of Easy-Twist wire connectors from NSI. These connectors feature a specialized design to install in half the time of a typical wire connector, saving you time and energy. The conical screw shape grips in fewer twists and the outside of the connector is textured with easy-grip ribs for comfortable twisting. The expert team at NSI designed these connectors with key convenience and performance features for electrical industry professionals, including ergonomic swept-back wings that provide a larger surface for exerting torque and a deep-skirt entry that protects against flashover or shorts. Our zinc-plated square spring will form a secure grip on your wires without pre-twisting and can even grip on a single conductor for increased safety. Designed for use on copper wires in size range of 18-10 AWG (minimum 3 #18, maximum 2 #12 with 1 #14), maximum temperature of 105ËšC (221ËšF) and maximum voltage of 600V building wires, 1000V in fixtures or signs. Experience the advantage for yourself to see how easy connecting wires can be.
