The Strain Reliefs for CAT6 Connector (Black) has a unique design that allows it to be crimped with the connector, making it an integral part of the complete assembly. Once terminated, the strain relief will not pull off the connector, and the electrical performance of the termination is optimized by maintaining the bend radius of the cable exiting the rear of the connector as per Category 6 requirements. It gives a professional high-quality appearance that achieves the look of a commercially molded patch cord with a field termination.
