Delineator mounting system

A delineator mounting system, comprising;

• a delineator with a lower end having a cylindrical inner surface and a lower edge;
• a coupler having an upper end, a transition portion, and a lower end;
• the coupler upper end having a cylindrical outer surface sized to closely interfit within the delineator lower end inner surface;
• the coupler lower end having a square cross-section outer surface;
• the coupler transition portion in a medial location of the coupler between the upper and lower ends;
• a mount adapted to be mounted to a pavement surface, the mount having a square cross-section inner surface sized to closely interfit about the coupler lower end outer surface;
• the delineator lower end interfitted with the coupler upper end, the coupler lower end interfitted with the square cross-section inner surface of the mount;
• with the coupler transition portion including a plurality of abutment projections extending from an outer surface thereof;
• with the abutment projections contacting the lower edge of the delineator;
• with the mount including a base having a generally-planar bottom surface, a top surface, and a cavity in the base located between the top and bottom surfaces, with walls in the cavity forming the square cross-section inner surface;
• with an upper fastener extending through the coupler upper end and delineator lower end, and a lower fastener extending through the coupler lower end and the walls in the cavity;
• and
• the base bottom surface partially defined by adhesive retention ribs having planar bottoms and spaced sides to form adhesive retention cavities, the base having a continuous side wall defining a generally-rectangular shape with rounded corners, the base having a generally-pyramidal top surface defined by buttress ribs extending from the side wall to central longitudinal ribs, and the base having walls defining a plurality of fastener through-holes extending through the base from the top surface to the bottom surface.
