IDEAL® WIRE-NUT® 30-3629 Model 73B® Twist-On Wire Connector, Non-Wing Shell Style, Fixed/Square Wire Spring, 22 to 14 AWG Wire, Solid/Stranded Copper Wire, Thermoplastic Polyester

The IDEAL® Wire-Nut® wire connector set new standards for innovation, quality and convenience when it was first introduced in 1928. As the first screw-on wire connector in America, it literally set the industry standard for years to come. With a fixed, square wire spring and a positive grip shell, the Wire-Nut® is perfect to twist-on with fingers for a secure connection that will last. The refined wire range makes it the best choice for fine stranded wire applications. The Wire-Nut® also features a tough, flame retardant thermoplastic shell that withstands environmental extremes and is reusable for easy circuit changes and addition. With five color coded models available, Wire-Nut® wire connectors will handle any job from as small as 22 ga up to 6 ga wire. Additionally, Models 71B®, 72B® and 73B®, in both color or black high temp, are the only twist-on wire connectors rated for use in air handling spaces. These connectors can be used on class 2 or low voltage connections inside plenums, ducts and other environmental air handling spaces without the need for a box. The black high temperature models are designed to withstand the extreme heat build-up found in high wattage light fixtures and signs.
