The Geerpres® Stainless Steel Downpress Wringer is electropolished to make the surface very smooth – so bacteria and foreign particles have nothing to attach themselves to. It is made from type 304 stainless steel to resist abrading, rusting, discoloring or staining in normal use. The downpress action wrings mops up to three times faster than conventional wringers to boost productivity and reduce costs. Wringer is autoclavable and available with a flat band for use on half-round buckets. For 16-24 oz. mops.
