This multifunctional tool comes with a built-in UTP/STP tester to help you quickly and accurately identify wiring faults in newly crimped or existing in-wall LAN cables up to 600 feet (183 meters).

Best of all, this multipurpose tool comes with a remote unit that detaches from the handle so you can check installed cables almost anywhere.
