Giganet Crimping Tool is a heavy-duty multi-connector tool that lets you customize your own network or telecom cables. Terminating 4-wire RJ11, 6-wire RJ12 and 8-wire RJ45 modular plugs is as easy as squeezing the easy-grip handle. The tool’s embedded blades strip flat modular cable and round network cable, such as Cat5e and Cat6, and cut cable as well.
