Over-designed, but to me as an engineer, that is good thing. Or at least better than under-designed though one should strive for balance with economy. Note the four shelf hanger mounts for the ultimate support. Given the carry-under configuration of the hanger wires and heavy perimeter wire, two and at most three would surely suffice. But I salute the designer, because he is my kind of person. Better to over than under design. CLICK the thumbnail for a detail view. See that this large Wire Basket rides below the shelf level.
