Super charge it by adding our jaws to any vise with 4" or 5" jaws (the most common sizes). These superb supplementary pieces will revolutionize what your Vise can do. Made of nicely finished, machined aluminum with fitted magnetic inserts. The set contains 6 pieces (3 pairs), giving you three new gripping surfaces: 2 non-marring smooth aluminum Jaws; 2 machined recesses (to securely grip pipe and other round objects on either axis); and 2 with rubber-faced surface (to provide for softer gripping). The modest cost of these 3 pairs of supplementary Jaws will be effectively paid for the first time you use them. You'll be glad you have them. Special Jaws shown mounted on two Garrett Wade vises. Very highly recommended.
