You need to do it in two stages, one for the section that clamps the wire insulation, then move it back to crimp the area that captures the wire.

This crimper is simple and has no ratchet.

The ratcheting type requires you to have it set up perfectly in the beginning. You can adjust the position and crimping pressure at any time until a perfect crimp is achieved by this tool.

It’s also very comfortable to use due to its ergonomics and the spring-assisted release design.

It allows you to see what you’re doing, gives room to hold the metal contact, and allows areas that you don’t want to crimp to be safe from accidental crimping. Also, the width of the jaws varies for the different crimp sizes to ensure precise crimping.
