3M 7000132915 Scotch® Buried Barricade Tape 303, CAUTION BURIED ELECTRIC LINE BELOW, 3 in x 300 ft, Red, 16 rolls/Case

It is a non-adhesive tape. The 303 is a polyethylene film marker ribbon that gets laid loose in the trench above the conduit or cable before backfill, not stuck to anything. Nothing to peel, no liner to discard.

The printed legend reads CAUTION BURIED ELECTRIC LINE BELOW, on red film. Red is the standard APWA color code for electric power lines and conduit, so the color and the wording both point an excavator at the same thing. If you are marking water, sewer, gas or communications instead, you need the matching color and legend, not this roll.

Scotch 303 is a plain polyethylene film marker, 4.0 mil (0.1 mm) thick with no metal core, so it is a visual warning to anyone who digs down to it. It will not respond to an inductive line locator. If your spec calls for detectable marking tape, you need a foil-cored product instead.

Each roll runs 300 ft (91.4 m) at 3 in (76.2 mm) wide, so one roll covers a 300 foot run of trench end to end. Figure your total footage plus overlap at splices and pull boxes when you work out roll count for a job.

The service range on the 303 is 0 to 120 degrees F (0 to 49 degrees C). That covers most backfill conditions, but hard winter work below freezing air temperature is outside the stated range, so handle and lay it when you are inside that window.

Yes, the 303 is compliant with RoHS 2011/65/EU, and 3M publishes a regulatory data sheet for it if your submittal package needs documentation. It is made in the United States, which matters on jobs with domestic-sourcing language.

It is built for buried service, printed specifically to warn of electric line below and laid over the cable before backfill. It is not a job-site cordon tape: the legend refers to something underground, so stringing it between stakes tells a crew the wrong thing. For fencing off a work area use generic CAUTION barricade tape and keep the 303 in the trench. Typical users are commercial construction, irrigation, utility and CATV crews, plus general industrial and MRO.
