  • Patent number: 11767649
    Abstract: A traffic control marker having a base with a bottom surface suitable for attachment to a road surface using mechanical fasteners and/or adhesive. A top surface of the base includes rounded edges, and a bottom surface with an inset groove pattern. A flexible outer tube is engaged over an inner tube, where both tubes have a circular cross-sectional configuration. The telescoping tubes are captured within a clamping assembly that is securely and mechanically engaged within a support cavity formed in the base. The base with the support cavity enables enhanced attachment to the road surface, as well as improved drainage through the traffic control marker. The interconnection of the base, tubes and clamping assembly enables the tubes to breakaway from the base after numerous vehicle impacts, and to resist removal of the base from the road surface.
