About this Product
Standard twist-on wire connectors feature ribbed caps and are designed to securely connect and insulate copper wires. The ribbed cap provides a grip for improved twisting and handling during install. Inside the shell, a zinc-plated square-wire spring firmly grips the wires as the connector is twisted, ensuring a secure and long-lasting hold. Flame-retardant shells offer durability, while the deep skirts prevent flashover and ensure excellent protection. Perfect for both professional electricians and DIYers, these connectors are compatible with a variety of wire sizes/combinations and offer long-lasting performance and reliability.
