The Original EZ-RJ45 CAT5e 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. 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. By reducing the distance between the wire twists and contacts, performance is optimized! WARNING:Platinum’s EZ-RJ45 connectors and crimp tools are designed to work as a system. Platinum Tools’ products are NOT intended to be compatible with other brands and such unintended use can result in bad connections, breakage, and human safety hazards, and will also void the warranty.
