Precision Ratcheting Crimper for Heat Shrink

This Klein Tools crimping tool is built for insulated heat shrink connectors from 20 to 10 AWG (0.5 to 6.0 mm²). Precision-forged single-piece jaws and a full-cycle ratchet mechanism deliver consistent crimp force on every cycle. Color-coded die positions match red, blue and yellow connector sizes for quick identification. Non-slip handles and a quick-release lever reduce fatigue during repetitive automotive, marine or outdoor wiring jobs.

Suits installers who need repeatable crimps

Technicians working with heat shrink butt splices, ring terminals or spade terminals in the supported wire range will benefit from the controlled ratchet action. The tool is not suited for users who need to crimp uninsulated terminals, open-barrel contacts or ferrules. Buyers who require a wider wire range beyond 10 AWG or a interchangeable die system should look at a different tool platform.

Crimp range fixed at 20-10 AWG for heat shrink

The three color-coded nests cover red (20-16 AWG / 0.5-1.5 mm²), blue (16-14 AWG / 1.5-2.5 mm²) and yellow (12-10 AWG / 4.0-6.0 mm²). This fixed range determines whether the tool matches the connectors on hand. No die changes or adjustments are possible outside these specifications.

Questions about this item

Does the kit include heat shrink connectors or must they be purchased separately?

The supplied kit contains the ratcheting crimper with colour-coded jaws for 20-10 AWG connectors; no heat shrink terminals are included and must be bought separately.

Which colour-coded jaw should I select for a 12 AWG wire?

Use the yellow jaw marked 12-10 AWG / 4.0-6.0mm² for 12 AWG conductors.

How does the 20-10 AWG range translate to metric cross-section on the job?

The tool covers 0.5 mm² up to 6.0 mm², matching the red, blue and yellow jaw markings for insulated heat shrink terminals.
