Knipex 97 51 13 cable crimper Crimping tool Black Blue Red Width 70 mm Length 191 mm Height 20 mm

The Knipex 97 51 13 cable crimper is an all-in-one tool for cutting, stripping round cables and crimping common RJ45 (8P8C) plugs. It crimps both shielded and unshielded RJ45 Western plugs and includes an adjustable retaining bracket that fits common RJ45 housings with closed and open bodies. The tool has a compact design—70 mm wide, 191 mm long and 20 mm high—with ergonomic multi-component handles for comfortable operation.

Advantages

Exact and consistent crimping is ensured by a parallel crimp and a self-releasing mechanism. Dual crimping points provide equal and balanced crimping pressure across contacts. A high-quality blade enables quick cutting and stripping of CAT cables. The adjustable retaining bracket increases compatibility with different RJ45 plug housings, and the compact dimensions make the tool easy to handle and store.

Suitable for

• Crimping shielded and unshielded RJ45 (8P8C) modular plugs
• Cutting and stripping CAT-style round network cables
• Network installation, repair and maintenance tasks in Ethernet environments

How to use

Place the stripped cable and the RJ45 plug into the adjustable retaining bracket, aligning the conductor ends with the plug contacts. Close the jaws to cut any excess conductor and to strip the cable where required using the dedicated blade section. Squeeze the handles firmly to perform the parallel crimp action; the self-releasing mechanism will open the tool when crimping is complete. Verify each crimped connection visually and, if possible, test the assembled cable with a network tester.

Usage recommendations

Use this tool for connectors with an 8P8C pin assignment and follow standard cabling practices (wire order, shielding termination). Keep the blade clean and replace it if worn. For reliable results, test cables after crimping and avoid using excessive force beyond the tool’s designed range.
