Clearly mark your underground utility with our DomedPost® Utility Markers. They combine rugged construction with high-visibility colors, conforming to DOT regulations. Choose from a wide range of post and cap color combinations.

Custom graphics are permanently molded into the product so they won’t fade, chip or peel. Anchor bar included with each marker.

Why Our DomedPost® Markers are Better

Premium Construction—outdoor durable marker posts are constructed of 100% prime high-density polyethylene. The UV-stabilized plastic prevents warping and is designed to withstand harsh outdoor environments for 20-20+ years.

Embedded Graphics—unlike surface or screen-printed marker posts, our custom graphics are permanently molded into the polyethylene material. Graphics won’t fade, chip or peel and cannot be scratched off, ensuring your underground equipment remains clearly marked. Permanent printing will even withstand harsh solvents used for removing graffiti.

Color Legends—high-visibility colors conform to US DOT regulations. Available in APWA uniform color codes (see chart below).
