The Olsa Tools Ratcheting Wire Crimper eases strain on hands thanks to large, non-slip handles that are designed to ensure a strong and comfortable grip. The ratcheting action allows the user to pause mid-crimp to get a better grip and will release automatically once the crimp is complete. It also conveniently enables users to secure a wire connector in the jaw before inserting the stripped wire into the barrel. Works with color-coded red, blue, and yellow terminals for 22 - 10 AWG wires.
