Klein Tools Ratchet Crimper AWG 20-10

This Klein Tools ratchet crimper handles non-insulated open-barrel terminals and receptacles from AWG 20 to 10. The jaws carry clear markings for 20-18, 18-14 and 12-10 sizes to speed up identification. A built-in ratchet mechanism forces a full cycle before the handles release, giving consistent crimps on every connector. The red nylon grips are shaped to reduce hand fatigue during repeated use.

Sustained crimping with adjustable force

The integrated star wheel lets you dial the crimp height up or down, so pressure matches each terminal batch without trial-and-error squeezing. A quick-release lever opens the jaws at any point in the cycle, preventing wasted connectors if a wire shifts. Because the ratchet only releases after a complete stroke, operators maintain uniform quality across long wiring looms in automotive or appliance work.

Replaces single-size crimpers for mixed-gauge jobs

Electricians who currently carry separate tools for different wire gauges can consolidate to this one frame covering the 20-10 range. The adjustable compression wheel removes the guesswork when switching between thin signal wires and heavier power leads. Buyers who only ever crimp one gauge, or who need insulated-terminal profiles, will not gain the same flexibility from this model.

Questions about this item

How much hand force is needed when the Klein Tools ratchet crimper runs through repeated AWG 20-10 crimps all day?

The precision ratchet structure automatically adjusts to the optimal position and releases the handles effortlessly after each full cycle, reducing hand fatigue during extended use.

What terminals and wire sizes must I already have to use the 25-pin crimping tool?

The tool is designed for non-insulated open barrel terminals and receptacles in the AWG 20-10 range, with jaw markings for AWG 20-18, 18-14 and 12-10.

Will the adjustable compression wheel on this 230 mm crimper work with older non-insulated terminals I already own?

Yes, the star wheel lets you increase or decrease crimping height so you can match the force to your existing non-insulated open barrel terminals.
