JAMCO Metal Shelving: Medium-Duty, Standalone, 48 in x 18 in, 54 in Overall Ht, 4 Shelves, Steel
The height of the shelves on these shelving units cannot be adjusted. Medium-duty open welded shelving units generally are sturdier and can hold heavier items than light-duty open welded shelving units, and their shelves are not enclosed with back or side panels. This allows items stored on their shelves to be seen more easily than if they were stored on closed shelving units.
