Description

Achieve Professional-Grade Connections with the Klein Tools Full-Cycle Ratcheting Crimper

The Klein Tools Ratcheting Crimper is the essential tool for electricians and DIY enthusiasts who demand precision and reliability in every connection. Engineered to crimp 10-22 AWG insulated wire terminals onto stranded copper wire, this tool takes the guesswork out of electrical terminations. Whether you are working on automotive wiring, marine electronics, or residential control panels, the integrated color-coded markings—Red (22-16 AWG), Blue (16-14 AWG), and Yellow (12-10 AWG)—ensure you select the perfect cavity for a secure fit every time.

Maximum efficiency is built into the design, utilizing a compound lever-action and narrow-span handles that put more crimping power into every squeeze while significantly reducing hand fatigue. The built-in ratchet mechanism is a standout feature, ensuring a full-cycle crimp that only releases once the connection is uniform and complete. For even more control, a built-in dial allows you to adjust the applied force, guaranteeing consistent results regardless of the terminal type. With its unique cavity design and dual-material molded comfort grips, this crimper provides professional durability and comfort for long days on the job.

Key Features

  • Precision Crimping: Specifically designed for insulated terminals on 10-22 AWG stranded copper wire.
  • Triple Cavity Design: Features three distinct cavities: 22–16 AWG (Red), 16–14 AWG (Blue), and 12–10 AWG (Yellow).
  • Full-Cycle Ratchet: Integrated ratchet ensures the tool doesn't release until a uniform, high-quality crimp is achieved.
  • Adjustable Force Dial: Allows users to customize the amount of pressure applied to the crimp for varied applications.
  • High-Leverage Handle: Compound action design provides maximum crimping power with minimal physical effort.
  • Ergonomic Comfort Grips: Dual-material molded handles help reduce hand strain during repetitive use.
  • Versatile Access: Unique cavity design allows for consistent crimping from either side of the tool.

Pro-Tip: To ensure the strongest pull-off force, always strip exactly enough insulation so that the wire strands extend slightly past the terminal barrel, but the insulation itself is seated firmly against the end of the barrel before crimping.
