Tracer Wire Versatile applications: Underground tracer wire, sometimes known as electrical wire tracer, is intended to carry a radio signal to accurately locate underground pipes and line. Can be installed underground, directly in contact with the soil, including in wet locations, so you can use it no matter your conditions. Flexible and easy to install, so you or your customers can easily install it, even around tight corners. RoHS compliant, so you can rest easy knowing it doesn't contain hazardous substances that could harm you, your employees or your customers (more information about this is in our Green Leaf Label). Operates in a wide range of temperatures, so this cable is suitable for installation anywhere outdoors in any part of North America.
