The EZ-RJ45 connector system has been used and endorsed by professionals worldwide for over 20 years. The design allows conductors to extend through the front end of the connector for easy verification of correct wiring order prior to crimping. The Platinum Tools 100010C has a large interior body cavity makes cable insertion easy with wire twists close to contacts for optimized performance. Connectors are crimped and excess conductors trimmed in one action with either the 100054C or 100062C crimp tools.
