Second order of these shelves for us. We have two in our garage and now two in the barn. They are super heavy duty and very easy to set up. The hardest part is inserting the cross pieces that hold the shelves up -- most pop right in but a few need wrestling with. I have set up all shelves by myself -- if you have something to brace the end pieces against,  you can do it with just one person. Excellent product and looks very nice.
