Crimping Tool Knipex 975110 Professional for RJ Plugs with Ergonomic Handles

Knipex 975110 Professional crimping tool for RJ plugs is a hand tool designed for precise termination of modular RJ connectors on patch cables and field installations. The tool provides controlled crimping action suitable for common RJ45 and RJ12/11 plugs, helping to create reliable electrical and mechanical contacts. Ergonomic handles reduce hand strain during repetitive use, making the tool appropriate for network installers, technicians, and maintenance staff who perform frequent cable terminations.

Advantages

The tool combines accurate crimping geometry with a durable construction to ensure consistent terminations. Ergonomically shaped handles improve grip comfort and reduce fatigue during prolonged work. A compact head design allows better access in confined spaces and around cable bundles. Overall, the tool is built to deliver repeatable crimps with minimal user adjustment and to stand up to daily professional use.

Suitable for

• Crimping RJ45 connectors onto Ethernet patch cables
• Terminating RJ12 and RJ11 plugs for voice and low-speed data
• On-site cable repair and re-termination in patch panels and wall jacks
• Field work by network installers and service technicians

Key specifications

• Function: manual crimping of modular RJ plugs
• Handle design: ergonomic handles for reduced hand fatigue
• Material: hardened crimping dies and robust tool body for repeated use
• Head design: compact for access in confined or crowded cable runs
• Compatibility: standard modular RJ plug sizes commonly used in Ethernet and telephony

How to use

Strip the cable jacket to expose the conductors, arrange wires according to the required pinout, and insert them fully into the modular RJ plug. Place the assembled plug into the crimping slot and squeeze the handles firmly and evenly until the crimp is completed. Inspect the termination visually and, if available, test the connection with a cable tester to confirm contact integrity. Follow standard safety practices and avoid excessive force beyond the tool's intended use.

Usage recommendations

Use the Knipex 975110 with compatible RJ plug types and standard stranded or solid conductors. Regularly inspect the crimping dies for wear and clean the tool to remove debris. For batch production or high-volume termination, verify crimps periodically with a tester to maintain quality and replace the tool if deformities or inconsistent crimps are observed.
