Abstract: A dual worksurface support is provided for electronic data processing equipment and the like, and includes two separate worksurfaces adapted to support different pieces of equipment thereon. The worksurfaces are interconnected by a linkage assembly which permits vertical adjustment of one of the worksurfaces with respect to the other, and includes left and right hand linkages located at the opposite sides of the respective worksurfaces, which rotate about at least one horizontal pivot axis. A rigid stabilizer bar has its opposite ends fixedly connected with the two linkages at locations concentric with the horizontal pivot access, such that rotation of one of the linkages is transmitted through the stabilizer bar to the other linkage to ensure that the opposite sides of the adjusted worksurface move vertically together without sagging or binding.
