The Rhino 3-Rail fiberglass underground utility marker post is rigid enough to be installed easily in most soil conditions and has the durability to withstand repeated impacts.

The 3-Rail design allows the post to bend over when hit, then snap back to its original upright position.

Fade Resistance

Rhino’s 3-Rail is saturated with bright pigments and UV stabilizers, and an extra layer of protection is added with Rhino’s SunCoat.

For even greater fade resistance, order the optional PolyTech CoatingT that protects from fading and fiberbloom for at least ten years.

A marker posts primary function is to support a warning message that will prevent an excavator from digging without calling for a locate. Our standard color fast decals use sharply contrasting colors and incorporate the international No-Dig symbol. This ensures that non-English speaking excavators will get the message! Use the 811 logo if you are a One-Call member in the United States.
