Description
This Underground Warning Tape – Communications (Non-Detectable) 365M is designed to visually mark the presence of buried communications cables and ducts. It is widely used by utility installers, fibre contractors, and civil engineers to avoid damage during excavation and trenching.
Manufactured from strong, 30-micron plastic, the tape is coloured bright green for visibility and industry-standard identification. It is printed with clear black text that reads “CAUTION COMMUNICATIONS CABLE BELOW” to warn workers of cable infrastructure underneath.
This version is non-detectable, making it suitable for jobs where visual trench identification is enough or where service maps and records already exist. The 150mm width gives wide trench coverage, and the long 365 metre roll is ideal for continuous runs with fewer joins.
