This is a simple design, but it may be useful to others so I decided to post it. My garage floor is uneven so I needed to place a shim under one of the wheels on my rolling tool chest to stabilize it. A wooden shim would suffice, but the swivel caster would tend to rotate and the chest would eventually roll off of the wooden shim. I created a simple plastic block that cradles the wheel. It serves as a shim while keeping the wheel from swiveling and rolling. The tool chest is now level and stable.
