The E-Z Red 3 Point Crimper, B7946, is a wire crimping tool that does a three-point crimp at one time and can crimp up to 4awg cables. The B7946 works in tight areas. It can be held with a 3/8” drive extension or ratchet, as well as a 19mm or 3/4" open-end wrench. This 3 Point Cripmer offers an adjustable wrench holding slot on the back of the tool and a hardended fine-thread drive screw for precise crimps. To use, ratchet the movable crimping head down onto the two-point base to make a three-point crimp. The B7946 can be used with a 3/8" impact battery drill for heavy duty wire, or in a vise for bench work.
