The single 12lb. capacity barrel is sized for larger material at up to 3 inches or more or just use the larger barrel for higher volumes of smaller material. The frame of this tumbler is the same as the QT66 so you can change out barrel configurations if needed. The rubber barrels on these tumblers are quiet and long wearing. The barrel is molded to have a decagon (10 sides) on the interior of the barrel to increase the tumbling action.
Base dimensions: 8.5″W x 11″L.
Barrel inside dimensions: 7 3/4″ depth, 6-3/4″ diameter.
