ACCEL's Wire Crimp Tool will have you making wires like a pro almost immediately. The molded non-slip hand grips and heavy-duty, hardened-steel frame fit perfectly in your hand, and an adjustable ratchet mechanism produces a perfect, factory-style crimp every time. The tool comes with three removable stripping/crimping die-type jaws – one for 7mm-9 mm spark plug wires, one for primary wire terminals, and one for pre-insulated terminals.
