The platinum tools 202016j ez-rj45 cat6+ 50/50 combo contains 50 each of ez-rj45 connectors and EZ strain reliefs. The patented 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. 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. reduces scrap, no wasted crimps. More reliable, higher performance. Crimp with the patented ez-rj45 crimp Tool.crimps And trims in one cycle. Manufactured in the USA. Patented. The innovative snag proof strain relief is designed specifically to be crimped with the ez-rj45 plugs. Two patent pending versions are offered for both the cat5/5e and the cat6 plugs. The primary strain relief of the plug locks the snag proof strain relief in place so they will not pull off, creating one, integral assembly. Once crimped, this design allows the plug's primary strain relief to relax slightly, preventing the cable pairs from being over compressed. This decrease in stress contributes to achieving peak performance. The tab on the strain relief is designed to extend over the plug's locking tab, making it snag proof when administering patch cords. Platinum tools, founded in 1997, was created based upon two very simple objectives. First, develop and source the absolute best possible solutions for the preparation, installation and hand termination of wire and cable. Second, implement an operational infrastructure that can deliver these products in an efficient, timely and high quality manner. All platinum products absolutely must satisfy three critical benchmark criteria, utility of function, quality of function, and economic value.
