The revolutionary design of the EZ Connectors transformed the way modular plugs are prepped and crimped. By allowing each individual conductor to completely pass through the connector and out of the front greatly simplifies terminations. Installers can easily see and verify the proper wiring order before crimping. The unique design also optimizes electrical performance by reducing the distance between the wire twists and contacts., 849160000488
