Coffee Laboratory HAND SCREENS are quality constructed, using premium kiln dried wood. The finished wooden frames are designed to stack on top of each other.
Round or oblong (Peaberry) hole apertures are custom punched with .004" tolerances, in to premium 20 gauge sheet metal plate, using computer numerical control (CNC) machine tools, eliminating partial holes.
Labels are clearly marked in 64th" increments, for agricultural grading applications, including coffee beans.
Although the millimeter equivelants on this popular chart, aren't exact, it fortunately doesn't have any real impact on the size analysis.
The New York Grading Chart has exact conversions, but both result in the same distribution because the tolerences are too small to impact 64th inch seperations.
