The Platinum 100003C EZ RJ45 Connector simplifies twisted pair terminations by allowing the wires to be inserted through the connector and out the front. This allows the technician to easily verify the proper wiring order. The electrical performance of the termination is optimized by pulling the connector down over the cable jacket and seating it tightly in the rear of the connector. This reduces the distance between the wire twists and contacts. When terminating your EZ connectors, twist all your extended conductors together into one tight bundle and then insert into your EZ crimp tool to be terminated. Tools designed for installing these connectors are the recommended Platinum 100004 EZ RJ45 Crimp Tool, 100044C EZ RJPRO Crimp Tool, and the 100054C EZ RJPRO HD Crimp Tool, each sold separately. The clamshell connector s simple one piece design with no bars or liners works with solid or stranded wire. For use in category 3, 5, 5E compliant data networks, the connectors are FCC compliant and UL rated.
