Aluminum Bar Clamp Rack

This is a short collage of pictures of the bar clamp rack I recently made. I didn't shoot any video because it was a very quick build.
With the right tools, it was easy to throw together and is helping out immensely with storing my aluminum bar clamps. I will definitely make more of these style racks with my other clamps...

Hi, I see you have both the rockler surefoot aluminum bar clamps and some Dubuque aluminum bar clamp. Can you please tell me your thoughts on the two brands? How thick are the walls on the aluminum bar clamps? Thanks
