ABSTRACT:
A lightweight vertical panel barricade for use on streets and highways in which a first vertical panel is supported and rigidly locked into place by the clamping effect of respective ends of leg support members acting against a wall support of a housing structure disposed at each end of the panel member. The leg support members are rectangular in cross-section and are virtually gripped on three side faces thereof by the housing structures in which they are pivoted, both in their extended, panel support position and their closed, storage position. A second panel member depending from and coplanar with the first panel member is surrounded by the leg members and provides a doubling of the reflective surface of the barricade.
