The Platinum Tools 105005 EZ-RJ12/11 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 prior to termination. Use the EZ-RJPRO HD™ Crimp Tool (P/N 100054) for single cycle crimping and trimming of the excess wire. FCC compliant and UL rated. Made in the USA. Patented. 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.
