This versatile shelving unit has been used in warehouses, workshops, garages, and basements. Each post is double slotted on 1-1/2" increments, meaning that you can adjust the shelf to your specific need. The units assemble by inserting the rivets into the slot and letting gravity pull the rivets into a locked position. Industrial quality shelving is now available at an affordable price for the average consumer, from small businesses to home owners.
