This Ferrule Crimper makes adding ferrules to your wire ends a breeze. Just strip your wire, add the ferrule to the end, and let the tool do the rest. You'll get an even, tight crimp every time.
It's a good practice to use ferrules on your wire ends, especially when you're tightening a screw or post down onto them to avoid fraying or damaging the wire strands and to ensure an even connection. We use ferrules specifically when installing an m-Unit, and we include them in every Deluxe Cable Kit.
