The crimping tool for Western connectors features an improved opening mechanism, an optimized design, and a reduced weight. It can be used for crimping 4-, 6-, and 8-pin Western connectors, as well as for cutting and stripping unshielded flat telephone cables. The precise crimping process is achieved through parallel crimping, which ensures consistently high crimp quality due to an integrated lock with an automatic release mechanism. Optimal power transmission is achieved through leverage, allowing for reduced fatigue during use. This tool is suitable for Western connector types RJ 10 (7.65 mm wide), RJ 11/12 (9.65 mm wide), and RJ 45 (11.68 mm wide) in a long version. The head is polished, and the handles feature two-color multi-component grips, along with an additional stripping tool for round cables.
