Blue Underground Marking Tape

Brady Underground Marking Tape 91603 identifies buried water lines with a blue background and black caution legend. The aluminum-backed material is metal detectable for locator equipment. Supplied in a 1,000 ft roll for extended trenching projects.

Replaces Faded or Missing Markers

Upgrade when existing tape has degraded or was never installed during original utility placement. The 5.1 mil thickness resists tearing during backfill operations. Worth the switch when code compliance requires detectable warning tape.

Detectable Aluminum Core

Handles continuous burial in trench environments where non-metallic tape cannot be located later. Runs out when the 1,000 ft length is exhausted or if a wider tape width is specified by local regulation.

Questions about this item

How wide is the 91603 tape and what thickness should I expect when laying it in a trench?

The tape measures 2 in wide and 5.1 mil thick, so it unrolls flat and stays visible after backfill.

Does the metal-detectable layer require any special grounding or connection during installation?

No grounding is needed; the aluminium core is embedded in the tape and becomes detectable as soon as it is buried.

Will the black legend on the blue background fade enough to need replacement after a few seasons?

The legend is printed on aluminium-backed HAWA material that resists UV and soil chemicals, so it remains legible for the life of the utility line.
