These shelving units do not require side or back braces, which allows items on their shelves to be accessed from all sides. Heavy-duty shelving units generally are sturdier and can hold heavier items than light-duty or medium-duty shelving units. They are used in industrial facilities for storing heavy tools, equipment, and supplies. Standalone shelving units cannot be expanded with add-on units, but multiple standalone units can be placed side-by-side, if desired. The top and bottom shelves on these shelving units bolt to the posts, which stabilizes the shelving and provides rigidity without requiring braces. The clips anchor and support the middle shelves on the posts, and the clips can be moved on the posts to adjust the height of the middle shelves.
