This 18" x 36" x 74" Chrome Wire Olympic Shelving Unit has the look of stainless steel without the cost. The nickle-plated chrome finish is an excellent choice for dry, low humidity environments and is coated with laquer protecting the finish to keep your unit looking newer longer. The Olympic Add-On Unit provides a complete add-on shelving unit in one box, making it an "easy order" and eliminating the need to choose each piece individually. The Add-On Unit includes: four shelves, two packs of split sleeves and two posts with leveling feet for minor adjustments on uneven floors.
