The IDEAL FT-45 Feed-Thru Mod Plug Crimp Tool is a simple, compact and highly effective crimp tool for installers and techs that terminates RJ45 connectors regularly. It has a single crimp cavity for RJ-45/8-position connectors that can be used with Feed-Thru, standard or shielded connectors for CAT-5E or CAT-6, a custom, replaceable, and heavy-duty cutting blade that will last for over 2,000 cuts and a mechanical design that requires only 1/3 to 1/2 the hand force of traditional tools to crimp the connector. No ratchet mechanism is needed and 1-handed crimping is possible. The tool is compact, 5 1/2 in. in length and weighs just over 1/2 lb. It has a textured grip, spring-loaded handle, locking hasp and has the 568A and 568B wiring scheme marked on it. A larger opening allows conductors to pass-thru without obstruction. The metal crimp cavity improves crimping consistency. The FT-45 cleanly shears the excess conductors and leaves a smooth flat finish to the end face of the connector. No protrusions or small lengths of conductor remain beyond the plastic face or the connector. This minimizes accidental shorting of conductors or inadvertent contact in plug jacks.
