Duramax Building Products 55.7" H x 35.4" W x 17.7" D Heavy Duty Multipurpose Shelving Unit

The modular plastic racking system is a smart, space-saving solution to simplify all of the storage solutions and provide incomparable rack solution for any environment. They feature ventilated shelving units in either 3, 4 or 5 tier configuration. These units are made of heavy-duty resin that will ensure that even your heaviest items are always stores safely. Each shelf can accommodate up to 150 pounds. Because it's plastic, the unit resists even the worst weather and maintains its structural integrity indoors or outdoors despite rain, snow, temperature changes and exposure to sunlight. The bottom feet protect against dirt and water damage, and the ventilated shelf construction prevents moisture build-up, which can lead to mold and mildew growth on your boxes and other vulnerable items.
