These quality stainless steel classifiers have rugged plastic bodies with stainless steel screens. They are 30cm/12" wide at the top and are especially tapered to fit in the top of a 5 gallon bucket. These sieves are new to Gemworld and are already popular with gold prospectors for their ease of use and leight weight.

The overall height is 3 1/2 inches (~9cm) and designed to allow for 4 of the classifiers to be nested with an overall height of only 8 1/4 inches (~21) as shown in the thumbnail image.
