BOUNDARY MARKER A boundary marker or delineator is disclosed comprising an elongate hollow cylindrical pole member normally held in an upright position with respect to a base member by means of a solid flexible support member. The cylindrical pole member is filled with a solidified foam and closed by opposed end caps held in place by a centrally-disposed rigid rod member threadedly connected to each. When utilized as a path delineator for moving vehicles, the boundary marker is capable of withstanding impact forces upon being struck and crushing forces upon being run over by vehicles of all types. |
