These replacement clamps from Spartan Power give you a straightforward, durable way to repair terminated cables using a 1\/4\" terminal bolt. Built from glass-filled nylon and 100% pure copper jaws, they are engineered to deliver better conductivity and longer life than cheap plastic clamps.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these clamps restore a damaged jump cable?\u003c\/h3\u003e\n\u003cp\u003eThey bolt onto cables that already have a ring terminal crimped or soldered to the wire end.
