If you have any mechanical aptitude, these are really easy to install, You will need large pliers or something like that to hold the lower body while tightening the main nut, but that's about it. They feel solid and the brake is easy to use, Seems to be a good value. My 200 pound metal workbench is easy to move around now to help maximize space. Understand that it will raise your bench/table by about 3-4 inches,
