Black strain relief works with EZ Squeeze connectors.
This boot has been designed to work with the EZ-RJ45 CAT5e and CAT6 connectors. This unique designed strain relief is crimped with the connector. Therefore it is locked it in place giving the look of a machined Patch cord crimp.
It helps maintain the bend radius of the cable and exits the rear of the connector to easily meet Category 6 and Category 5e requirements.
