The 3M 7000133203 is a detectable buried barricade tape from the Scotch 400 Series, engineered for accurate underground utility marking. This tape is embedded with a detectable element that allows locating equipment to identify its position beneath the surface without excavation. It carries a printed warning message reading CAUTION BURIED TELEPHONE LINE BELOW, making it appropriate for marking buried telecommunications infrastructure. Installation is performed during trenching operations by telecom and utility contractors before backfill is completed. The tape serves as both a visual warning during any future digging and an electronic marker for locate crews.
This tape is used in underground utility installation and protection applications, specifically for marking buried telephone and telecommunications lines. It is suited for residential, commercial, and municipal utility projects where telecommunication conduit or direct-buried cable requires surface-visible and electronically detectable identification. Contractors install it at a consistent depth above the utility during backfill, following local dig-safe and utility protection standards. It is sold in roll form with a minimum order quantity of 4 rolls.
Designed as an OEM-style marking solution for buried telephone and telecommunications utility installations requiring detectable underground warning tape.
Installed by telecom, utility, or excavation contractors during active trenching before backfill. The tape should be placed at the required depth above the utility per applicable local codes and dig-safe regulations. Keep the tape taut and continuous along the full run of the buried line to ensure reliable detection. No energized systems need to be de-energized for tape installation, but all applicable trench-safety and confined-space protocols must be followed.
