The Member's Mark 24-Bin Rolling Rack is great for schools, offices, workshops, restaurants, garages or just about anywhere that requires multi-storage containers. The 24-count polypropylene bins are designed to slide out easily and lock for safety and convenience. The unit comes with ten removable bin dividers to help separate smaller items. The rack has four 3-inch caster wheels that allow you to move it with ease. Two of the wheels lock for stationary use and safety.
