These half round stainless steel buckets are great for anyone needing a two-bucket mopping system. The buckets come as a package of 2, and each one is 5 gallons. The buckets themselves have an overlapping lip for stability when fastened together. The tapered sides allow for nested, compact storage. Permanently etched gradations enable easy, accurate mixing. Safe, easy-lift bails and handles make emptying your buckets a cinch. These buckets are the only steel/metal buckets that offer these features. Half round buckets must be used with a flat band wringer, just like our stainless steel flat band mop wringer.
