Round Bench Dogs are suitable additions to any existing or new workbench. By drilling 3/4˝ holes at regular intervals, you can turn the top of our bench into a versatile clamping table. Our round bench dogs are milled from aluminum stock with a side spring to support height adjustment. The face is cross hatched faces, off set several degrees from the vertical to firmly hold your work. They are 4-3/4˝ long with a 11/16" x 1-1/4˝ work face and suitable for benches up to 4˝ thick.
