Placing the hook within the head of a Regal Vise is very important. Due to the pressure the vise head exerts, the hook must be placed well within the limits of the head surfaces. See figures 1, 2 and 3 for proper hook
placement. Failure to properly place the hooks may result in “chipping” of the head or the hook may dislodge from the vise under pressure. See
figures 4, 5, and 6 which depict improper hook placement.
