Wedges Print
Gruber plastic wedges and quality red oak custom wooden wedges are 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!!
