1 white metal shelving unit that attaches to the wall. Like the stuff they sell at Home Depot (which is where I bought it years ago). Shelf is 6' long and 16" deep. Standards are 12" long. Replacing all shelving in garage with other stuff. Don't want to sell it, I want to give it away! I will give it to first person who PM's me and comes to my place to pick it up. Once this ad is gone, the deal is done.
