Underground Utility Markers

Clearly marking underground utility lines can help avoid excavation accidents that lead to deaths, injuries, service interruptions, environmental damage and liability. Here you'll find pipeline and underground utility signs, labels and marker posts for gas pipelines, water and sewer lines, petroleum pipelines, buried electric cables and more.

  • Choose signs in various formats for post- or surface-mounting; Pipe markers are available in various sizes for different pipe diameters

  • Use indoors or outside - protective laminate layer resists moisture, abrasion, UV and chemicals

  • All are made-to-order in the USA and usually ship within 2 business days
