F4P DBTAPE2-C – Frequently Asked Questions

1) Which width of fiber optic caution tape should I use over a buried conduit run?
The F4P red underground caution tape comes in 2 inch, 3 inch and 6 inch widths, all on 1000 ft rolls. Narrow 2 inch is typically run over a single small duct or drop; 3 inch is the common general-purpose utility marking width; 6 inch gives the widest visual footprint over a multi-duct bank or wide trench where a backhoe operator needs to see it as soon as the bucket breaks into the fill. All three carry the same print and the same 5 mil thickness, so the only decision is how much trench width you want covered.
2) What exactly is printed on this red F4P underground warning tape?
The F4P tape is printed with buried-line caution wording, in the two messages the line is produced with: CAUTION ELECTRIC LINE BELOW and CAUTION FIBER OPTIC LINE BELOW. The red version is the fiber optic marker, printed CAUTION: BURIED FIBER OPTIC LINE BELOW. Specify the message you need when ordering so the tape matches the utility actually in the trench; an electric message over a fiber run misleads the next crew that opens the ground.
3) Is this tape available in orange as well as red for utility line marking?
Red and orange are both offered in the F4P underground caution tape line. Red is the fiber optic / telecom marker on this product, printed with the buried fiber optic warning, while the line also covers electric line marking. Pick the color your utility or municipality has standardized on for the service in the trench.
4) How much trench does one 1000 ft roll of F4P caution tape cover?
Each roll is a continuous 1000 ft length, so one roll marks roughly 1000 linear feet of trench in a single pass with no splices. If you are laying tape at two depths over the same run (a common practice on deep duct banks), figure two rolls per 1000 feet. Overlap at roll ends so there is no unmarked gap.
5) Can I use this red tape over a buried electrical feeder instead of fiber?
The F4P underground caution tape line is made for marking underground utility lines, both electric and fiber optic, and is produced with either an electric line or a fiber optic line message. The red product is the fiber optic marker. For an electrical feeder, order the electric line message rather than running fiber wording over a power circuit.
6) Does buried caution tape replace a tracer wire for locating a fiber line later?
No. Buried caution tape is a visual warning for a crew that has already opened the ground, printed CAUTION: BURIED FIBER OPTIC LINE BELOW so the excavator stops before the bucket reaches the duct. It does nothing for an above-grade locate. If you need the run found with a locator from the surface, you still need a tracer wire or a detectable warning tape pulled in with the duct.
7) Will 5 mil polyethylene caution tape hold up to backfill without tearing apart?
At 5 mil, this polyethylene tape is substantially heavier than the 2 to 3 mil barricade tape used above ground, which is what lets it survive being covered with backfill and stay legible in the ground. Lay it flat on a smooth lift of fill rather than directly on rock or sharp spoil, then cover with fine material before the heavier backfill goes in.
