Abstract
A highway delineator device comprising an elongate tube having a bottom end, a top end, an inside surface, and an outside surface, and configured for use as a highway delineator. The bottom end of the tube comprises means for connecting the tube to a base support in such a manner that the tube is in a vertical configuration, and the top end of the tube having at least three different cross-sections comprising (i) a top cross-section flattened together with opposing inside surfaces sealed together to fully close the top end of the tube and having opposing outside surface in parallel relationship for receiving a top edge of reflective material without curvature, (ii) an intermediate cross-section having an elongate gap extending between the opposing inside surfaces, said outside surfaces along the gap being slightly arcuate to provide a flattened surface for receiving a lower section of reflective material with moderate curvature, and (iii) a lower cross-section having a circular configuration. The flattened portion of the top of the delineator further comprises a reflective marker attached to its outside surface.
