Our Large Steel Bending Pliers, with their box-joint construction, are perfect for those extra-heavy bending jobs. The jaws of these pliers are concave/convex for shaping shanks, and the edges are rounded so they will not mar metal. When using to shape parts to the tube diameter, they will bend the parts to fit down to a ⅜” diameter tube. The Pliers overall length is 5 ¾”.
