This heavy-duty five-shelf unit is made of industrial grade steel with a durable silver-vein finish. Z‐Beam design beams add strength and rigidity. The shelves with particle board decking can be adjusted in 1‐1/2-inch increments. The unit includes a post coupler to make assembly faster and easier, no nuts or bolts required. It can be assembled vertically as a shelving unit or horizontally as a workbench.
