Platinum Tools 202035J Strain Relief for EZ-RJ45 CAT 5e Connectors & Shielded CAT 5e Connectors are an innovative snag proof strain relief system that is specifically designed to be crimped with the EZ-RJ45 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 plugs primary strain relief to relax slightly, preventing the cable pairs from being over compressed. The tab on the strain relief is designed to extend over the plug's locking tab, making it snag proof when administering patch cords. The 202035J provides a decrease in stress that contributes to achieving peak performance.
