Now you can use your steel-jawed vise to clamp painted and highly polished parts, soft alloys, or irregularly shaped components, without fear of cosmetic or structural damage. These soft polyurethane pads are durable and resistant to oil. They slip right over the jaws and are held in place by magnets when the vise is open. During use, the knurled faces provide a secure grip without harming the part. As the vise is tightened, the pads will conform to virtually any round or irregular surface providing even more holding power. They return to original shape after use. Pads are 4 3/8in. L x 1/4in. W.
