What every grocer knows is that it's not how deep the shelves are that's important, it's the amount of usable "facing". This sturdy and clever system packs the equivalent of over 44' of shelf facing into a cabinet 34" wide, 20" deep, and just over 6' high — using 42 height-adjustable shelves. Best of all, it can be used in a free-standing cabinet in existing kitchens, or as a built-in for new kitchens.
