Trident RhinoDome Marker Post | Dome-Style Utility Marker
Trident RhinoDome Marker Post | Dome-Style Utility Marker — Product Overview
Trident RhinoDome Marker Post is a dome-style utility marker designed for long-term visibility and durability in the field. Permanent hot-stamped graphics keep your warning message clear and compliant—never peeling like surface-applied stickers. Unlike the RhinoDome Test Station, this version is built purely for line marking and identification, not tracer wire access.
Made from RhinoPoly (Trident’s proprietary thermoplastic blend), the RhinoDome Marker Post performs in extreme temperatures from −40°F to +150°F and is UV-tested for 10+ years of outdoor use. Its thicker .125" wall and oversized 21" dome topper provide unmatched stability and 360° visibility. Backed by a 10-Year Warranty.
