Accufill Ring for 3-Lb Barrels
The Accufill Ring (actually a gauge or template) is just the right size to make sure you have filled your barrel properly. Place the AccuFill Ring on top of the rocks in the barrel and when the top of ring is level (flush) with top of barrel (see second photo), the rocks are at the proper level. Remember, you can make up for lost volume by adding the Ceramic Shape Mix. One ring will measure all your 3-Lb barrels--both Lortone and Thumler.
