When you're terminating wires, you'll need to crimp them. And if you're a professional, you'll probably be crimping a lot of wiring. Which means a manual crimping tool is going to give you a serious case of hand fatigue. Instead, why not opt for a battery-powered or electrical option? Quicker and easier than manual crimpers, most of our powered options will automatically retract and open to let you know your crimp is complete, taking the guesswork out of it.
