This is a Thumler R3 Rubber Molded Barrel, a three pound capacity rubber barrel that fits the Thumler's Model A-R1, Model A-R2, and Model T rock tumblers. It includes the soft rubber barrel, lid and sealing ring.
TIP: Get an extra barrel just for the polishing step. This significantly reduces the possibility of grit contamination.
