we'll see if I can post an image. This is a pic of my foot vise in the shop here at home. Same brand, different dies. I'd like to find another for the trailer shop. I use it most days. Twisting the most or just to grab for a third hand. I also use mine for distance marking (bends) of up to 1/2 square or rounds. Ash tray sets on it too.
Mine ain't bolted down and in my small shop, it can be moved around as needed.
