The plurality of pickets and posts 142 forms the load path that transfers the load of the invention 100 to the supporting surface 143. The invention 100 is suspended from the rail 141 of the fence 104. The invention 100 is a table comprises a counter plate 101, a bracing plate 102, and a rail hook 103.
