Knipex 97 53 04 Self-Adjusting Lever Crimper 7-28 AWG

Knipex Self-Adjusting Crimper for 7-28 AWG

The Knipex 97 53 04 is a self-adjusting lever crimper built for electricians and installers who need reliable terminations across a wide wire range. It handles conductors from 7 to 28 AWG and strips cables up to 5 AWG. The automatic jaws adapt to each size without manual changeover. Multi-component knurled grips resist slipping during repetitive use.

Consistent Crimp Force Under Repetitive Load

The lever mechanism multiplies hand force so each crimp seats fully even after hundreds of cycles. Self-adjusting jaws maintain parallel alignment, preventing the uneven compression that causes loose terminations on smaller gauges. Hardened die faces resist deformation, keeping crimp height stable across the full 7-28 AWG span. No manual die swaps means no downtime between wire sizes.

Quick Setup With Reversible Jaws

Jaws flip from either side so you change capacity without disassembly, cutting setup time on mixed-gauge looms. Knurled multi-component handles stay secure with oily or gloved hands. The only common error is inserting the wire past the locator, which yields an incomplete crimp; the tool gives tactile feedback when the lever bottoms out.
