Abstract: A shelf upright extension kit with an elongated bottom extension rail with a transversely extending keyway and first and second extension panels. The extension panels each define a plane having first and second major surfaces, a pair of opposed ends and a pair of opposed edges. Each extension panel is fitted with a key configured and arranged for cooperatively engaging the keyway in the extension rail. The key extends within the plane of the extension panel proximate and parallel with a same edge. Included in the extension panel is a notch in a corner opposed to the key within the plane of the extension panel to allow the top end to fit flush with a bottom end of a side panel and the rear edge of the extension panel to fit flush with a wall.

Abstract: A twin beam shelf including a wood grain support structure defining a first major surface, a second major surface and longitudinally spaced front and rear edges with a rabbet extending along the front and rear edges. The front and rear wood grain beams are configured and arranged for cooperatively engaging the front and rear edges of the support structure to form a flush adhesive joint. The front and rear wood grain beams either extend laterally beyond the second major surface of the support structure or are flush with both surfaces of the support structure.

Abstract: The present invention is a wall shelf support assembly. The wall shelf support assembly includes first and second transversely elongated rails each with a transversely extending keyway and first and second side panels each defining a plane. The opposing side panels each have first and second major surfaces, a pair of opposed ends and a pair of opposed edges. Each panel is fitted with first and second keys configured and arranged for cooperatively engaging the keyways in the first and second rails respectfully. The keys extend within the plane of the side panel in opposite directions from opposed ends proximate to and parallel with a same edge.
