Abstract
A series of horizontally spaced vertical blades each has a uniform thickness and opposite vertical edge portions projecting in opposite directions, and a lower end portion of each blade is locked within a slot of a corresponding cylindrical base member by a pair of retractable cross pins. The base members are mounted on interlocking joints of a series of base rail sections which precisely space the blades and mount on the top surface of a concrete highway median barrier. Bolts extend downwardly through the base members into anchors expanded within the barriers and secure each base member and the underlying rail sections of the barrier. Each blade and corresponding base member are rotatably positionable on the underlying rail sections which have upward projections for locating the base member and blade at a selected predetermined angle. The upper end portions of the blades may be releasably connected by a horizontal cable for use in high wind areas.
