This is a great accessory for your Framon Code Machine. This vise will hold the wide, deeply milled blanks such as X160, X161, X176 and X184 that tend to tip in the standard vise. The reverse side of the vise has a built-in tip stop and special millings to hold all of the interchangeable core keys firmly. The vise eliminates the need for shims and wires to hold these blanks. Fits Framon #1 or #2 Code Machines. PART NO. F2SH050 – For The #1, #2, & #2D
