Mold Supplies and Accessories

From Gruber Systems and Marshall Gruber Company
Mold wedges from quality hardwood or durable plastic are used for a variety of purposes around the shop, but are used primarily to level molds when casting cultured marble, solid surface or other cast polymer material - or to assist in demolding the cast part from the mold. Other uses are limited by your imagination!!
  • Choose from high quality durable plastic wedges in a variety of sizes, or quality red oak hardwood wedges.
