Type 3 object markers are essential safety devices designed to warn motorists of potential roadway obstructions. Constructed from high-quality .080 aluminum with standard 3/8" mounting holes and radius corners, these markers meet both DOT and MUTCD state and federal guidelines for visibility and safety. Featuring high-intensity and diamond-grade reflective surfaces, these OM3-R markers provide clear visibility during day and night conditions. When installed, the edge of the object marker closest to the road user should align with the nearest edge of the obstruction. For guardrail and roadside appurtenances, the markers utilize alternating black and retroreflective yellow stripes angled at 45 degrees, providing a clear visual warning to approaching drivers.
