Use this Thermo-Loc Form Block to create custom workholding fixtures that allow flexibility in a holder. The many smaller cavities are used without the divider to create fixed holders for items such as pendants or fobs. With the divider, making a flexible hinged holder is easy! This allows even longer items (such as bracelets) to be held securely and then engraved without chatter. These custom workholding fixtures will work with most engraving blocks and vices.
