Precision Ratchet Crimper for AWG 20-10 Terminals

This Klein Tools crimper is built for electricians and technicians who terminate non-insulated open barrel terminals. The precision-profiled jaws cover AWG 20-18, 18-14, and 12-10 ranges with clear markings for quick size identification. A robust ratchet mechanism auto-locks at the correct position to guarantee consistent crimps without damaging terminal housings. Textured nylon handles reduce hand fatigue during repetitive wiring tasks.

Upgrade from Manual Crimpers for Repeatable Results

The ratchet system replaces basic pliers or fixed-die tools that rely on operator feel, eliminating inconsistent compression that leads to loose connections. The adjustable star wheel lets you fine-tune crimp height for different wire and terminal combinations, so the jump is worthwhile when you need documented repeatability across AWG 20-10 sizes. It is not suited for insulated terminals, closed-barrel contacts, or heavy-gauge cable lugs beyond the stated capacity.

Simple Setup with Quick-Release Lever

The tool ships ready to use; select the marked jaw nest, set the star wheel for the terminal thickness, and squeeze until the ratchet releases. The quick-release lever opens the jaws instantly if a terminal is misaligned, preventing stuck cycles. The most common issue is applying force before the ratchet fully engages, which can deform the terminal; always confirm the lock position before completing the stroke.

Questions about this item

What wire gauges do the AWG 20-18, 18-14, and 12-10 markings on the jaws cover?

The three marked stations cover non-insulated open-barrel terminals from AWG 20 through AWG 10 in three overlapping ranges.

How do I use the star wheel adjuster to set the crimp height for a specific terminal?

Turn the star wheel to raise or lower the anvil until the ratchet releases at the exact compression the terminal manufacturer specifies.

Are replacement jaws or crimp dies available for this ratchet crimper?

The supplier lists replacement heads as a separate accessory line for this tool family.
