Keene’s stackable Blue Classifier sieves enable you to stack several sieves together for graduated classification. The sieves lock into position with a 1.5 inch gap between the screens which allows you to stack screens and size your material all at once. The compact stack-ability makes transporting into remote areas easy as is storage and shipping. 13 sieves stack up into a 12 inch tall stack. The Blue Sieves fit inside most 20 litre buckets and are constructed with stainless steel mesh and high impact plastic frame.
Dimensions: Top 14” - Bottom 11“ - Height 3” and the mesh is 30 or 1/30 of an inch
