Knipex 97 51 12 Crimping Pliers for Western Plugs RJ12 RJ45 200mm

The Knipex 97 51 12 is a 200 mm crimping plier designed for Western-type modular plugs RJ 10, RJ 11/12, and RJ 45, covering the full range of common telecommunications and network connectors. The tool combines a parallel crimp mechanism with a ratchet lock to deliver consistent, repeatable crimps on every cycle. An integrated length cutter and stripping blade for flat, unshielded telephone cables make this a complete single-tool solution for data cable termination.
