Blue Classifying Sieve - 20 Mesh
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 a breeze, not to mention storage and shipping becomes a snap. 13 sieves in stack up into a 12 inch tall stack! The Blue Sieves fit over most 5 gallon buckets and is constructed with stainless steal mesh and high impact plastic frame.
