I purchased the leveling casters for a cabinet underneath my workbench. The leveling action worked flawlessly. I was able to set the height of the workbench so that it did not interfere with the infeed and outfeed requirements of the surrounding tools. The cabinet remains steady and does not slide when force is applied from the sides. As the cabinet is fairly heavy, especially with all the drawers full, I needed heavy duty casters for the job. These exceeded expectations.
