Its easier than it looks
I was doing a small accessory job and wanted this industrial look without the high cost of ordering it custom. I decided to go to Home Depot and do it myself. This is not something I usually do but I was under a specific budget and I could not sacrifice the end result. Honestly, it was easier that I thought. Just buy the necessary items, spray paint, screw together and your set to hang on the wall. Use anchors or studs to ensure strength because those brackets are solid steel and are heavy by themselves. Pictured right is the end result. It was a small bathroom so I did fairly thin shelves. Added baskets and some random accessories and it looked straight out of a magazine.
