These SCHWAIGER® universal crimping pliers are designed for connecting all 4, 6 or 8-pole modular (RJ11 / RJ12) or Western plugs (RJ45) to an unassembled telephone cable. For the best results, the pliers are made of high-quality metal and with the non-slip plastic handle always offer you a firm hold while working. With just a single tool, round and flat cables can be easily shortened to the desired length, simply stripped and then professionally crimped.
