This two-sided Thermo-Loc® Form Block lets you form precision fixtures from thermoplastic materials such as Thermo-Loc, Jett Sett, and Plastiform for secure, chatter-free engraving, stone setting, and finishing. Use the small cavity grid without the divider to make rigid, single-piece holders for pendants, medallions, and small parts.
