3M EMS Warning Tape 7900-XT Tape offers a maintenance-free solution for marking and locating underground utilities. It helps eliminate the problems and costs associated with traditional tracer wires and test stations. This 3M underground cable tape features embedded markers that work seamlessly with 3M™ Dynatel Locators 7000 Series, providing accurate and reliable location data without requiring external power sources. Ideal for open trench applications, the 7900-XT series incorporates high-strength core materials that alert excavators to the presence of underground assets. This helps to avoid accidental damage during excavation.
This 3M EMS 7900-XT Tape ensures efficient, quick and reliable underground asset detection. With unique RF frequencies, the tape’s embedded markers provide an early warning to excavators, reducing the risk of accidental damage to utilities. The high-strength core materials ensure durability, while the independent operation of each marker guarantees accuracy even if part of the tape is cut or removed. Offering maximum burial depths of 4 feet (1.2 m), this tape is available in multiple bright colours. This makes it easy to identify different utilities across power, water, gas, and telecommunications industries.
