TRIPP LITE's T100-001 crimping tool is a heavy-duty multi-connector tool that lets you customize your own network or telecom cables. Terminating four-wire RJ11, six-wire RJ12 and eight-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 CAT 5e and CAT 6, and cut cable as well.
