Modular MaxiRack features a split-post design that allows you to create the storage system or workcenter you need. Basic 72"H units split into separate 36"H units to create instant counters or workbenches. A hammer is all you need for fast easy assembly—no nuts or bolts to tighten. The heavy gauge steel frame combined with particleboard shelves gives you 1500-lbs. evenly distributed capacity per shelf—5000-lbs. capacity overall. Sturdy double rivet construction all around supports heavy loads. Shelves adjust on 1 1/2" centers. Baked enamel finish resists rust and corrosion. Color: gray. Made in USA.
