Behind a single cabinet door on this 46 inch cart sits enclosed storage for the things that should not sit out in rain, and around it are 3 open shelves, a spice rack and a towel rack for the things wanted within reach. The stainless steel countertop runs 35.5 by 20 inches, rustproof and heat-resistant, and takes 88 lbs of food, boards and serving dishes. The middle shelf is the heavy one at 660 lbs; the top and bottom shelves carry 77 lbs each and the spice rack 22 lbs. Four swivel casters, all lockable, roll the 74 lb frame between the kitchen door and the grill and then hold it in place. Heavy-duty metal makes up the structure, which is what supports that load spread across a cart this size.
