I really like these but they might be too heavy. I have two of these under my photo booth and they seem to have flat sides where they used to be in my garage. When I moved it the other day, it looked like a shopping cart with a wheel; ba-tum, ba-tum, ba-tum. Also, the flanges on the wheel cover fit snugly into the main L-shape that is attached to your body. Unfortunately, the extra thickness around only *part* of the outer L-bracket means it won't fit snugly in the slot you cut out in your case.
