This unit is great for schools, offices, workshops, restaurants, garages or just about anywhere multi-storage separation and containment is needed. The 24-count polypropylene bins are made to slide out easily and lock for safety and convenience. The unit comes with 10 removable bin dividers to help separate smaller items and four 3-inch caster wheels which allow you to move the rack with ease. Two of the wheels lock for stationary use and safety. If you are looking for permanent placement, this unit also comes with four leveling feet.
