Simply pull the connector down over the cable jacket so that insulated wires go through the nose of the plug. Inspect the wiring prior to crimping the connector. It's done in one step with the EZ-RJ45 Crimp Tool. Make faster terminations and reduce wasted crimps and scraps. Backward compatible with CAT5 and CAT3 cable. Work with solid or stranded cable. FCC compliant and UL rated. Also available in packs of 50 and 100, and in a shielded version.
