Garage Shelf, NO WELDING OR BOLTING REQUIRED

I needed to create a shelf for my garage with a specific depth to accommodate two cars. I already had shelves in place, but they were too deep, preventing me from parking a second car. I was constrained by the depth of a curve in the corner of the garage. Additionally, I wanted the shelf to be snap-on, so I decided to use a tube that I could cut using a tube laser to achieve the hooks that would snap onto the vertical posts.
