Double-surface contact tray loading base

A double-surface contact tray loading base, comprising

• a generally planar horizontal loading surface that is configured to store items thereon, wherein the horizontal loading surface has a top, a bottom, a front edge, a rear edge, and side edges;
• a hook defining a hook lug that has a horizontal portion and a vertical portion extending upwardly from the horizontal portion, wherein the vertical portion has an inner surface and an outer surface, and the horizontal portion of the hook lug is attached to and extends directly from the rear edge arranged on an outer end of the loading surface;
• a support plate that is attached to and extends downwardly from the bottom of the loading surface, wherein the support plate has an inner surface and an outer surface;
• a longitudinal stopper wall extending upwardly from the loading surface;
• and
• a transversal stopper wall extending upwardly from the loading surface and generally perpendicularly from the longitudinal stopper wall;
• wherein a gap is defined between the vertical portion of the hook lug and the longitudinal stopper wall;
• wherein the loading surface, the hook lug, the support plate, the longitudinal stopper wall, and the transversal stopper wall form a unitary one-piece structure;
• wherein the vertical portion of the hook lug is configured to be inserted within a mounting hole of a vertical support structure to suspend the double-surface contact tray loading base from the vertical support structure with the vertical support structure being wedged between the inner surface of the vertical portion of the hook lug and the outer surface of the support plate.
