Great for high-volume storage, the Advance Tabco EGG-1836 wire shelving unit has four levels that can hold 800 pounds of evenly distributed weight each. Its wire construction ensures air circulates properly, keeping dust off shelves in dry storage and ensuring cooling is uniform in cold storage. Because the components are coated in green epoxy, the unit can be used in walk-in coolers, dishrooms, and other humid areas. It’s shipped knocked down and is convenient to assemble since the posts are numbered. Each post has an adjustable foot that maintains stability on uneven surfaces.
