Gorilla Nuts are revolutionary twist-on wire connectors featuring a soft over-molded exterior for indoor and dry electrical splices. The cushioned over-molded exterior helps prevent pain, chapping, cracking and nerve damage in electricians' fingers. Gorilla Nuts are rated #1 for overall comfort, while making a quality connection. Wires are held tight with the first twist due to the Sharp Wire Technology. A flexible workskirt protects over-stripped wires and folds to meet box fill space needs.
