This is the complete sifter drum assembly for The Kief Thief. This sifter drum features a 150 micron stainless steel mesh. The size of the holes in this mesh are slightly larger than our standard 100 Micron screen that comes standard with the stock Kief Thief. This size mesh is perfect for larger more developed trichomes that may be too large to make thier way through a 100 Micron screen. It includes sifter drum assembly including tension rods, stainless steel access cap, and bearing shaft. The replacement Kief Thief sifter drum is perfect for customers who are wanting to do multiple back to back runs quickly without having to empty and clean out the drum between runs. They are also handy for customers that want a dedicated drum for each specific type of material.
