MODULAR PLUG CRIMP TOOL: FT-45 is a simple, compact and highly effective modular plug crimp tool for installers and techs to terminate RJ-45 connectors on to CAT5e, CAT6 or CAT6A twisted pair cable.COMPATIBILITY: This replacement blade works with IDEAL 30-495 FT-45 Feed-Thru Crimp Tools. Blade is ideally designed for trimming excess conductor length on feed-thru connectors.PRECISE TERMINATION: During crimping, the FT-45 crimp tool cleanly shears the excess conductors and leaves a smooth finish at the end face of the Feed-Thru connector. This minimizes accidental shorting of conductors or inadvertent contact in plug jacks.
