Adapter Grinder Lid

This patent pending accessory screws onto the top of the jar and allows you to remove the top half of the Tetra Grinder and grind either directly into the large compartment and agitate until you have collected the desired amount of pollen or you can grind directly into the ground herb storage compartment and keep all of the pollen with your herb. The threads of our Aluminum Grinder Lid fit the Tetra Grinder threads and 80% of the other 2 inch grinders on the market.
