The Platinum Tools 100003C EZ-RJ45 Cat5e connectors simplify 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. 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. Reducing the distance between the wire twists and contacts improves performance! The Platinum Tools EZ-RJ45 Crimp Tool makes terminating these connectors EZ.
