These vintage cast iron workbench legs are easy to use. Just attach them to your workbench frame with the appropriate tools. When installing, make sure the legs are firmly fixed to ensure stability. As for maintenance, keep them dry to prevent rust. If they get dirty, you can clean them with a mild soap and water solution. Avoid using abrasive cleaners as they may damage the surface of the cast iron. Also, be careful when moving them as they are quite heavy.
