The CF8 rough finish stainless steel (equivalent to type 304) body and large, 12” (305) diam. grate in this floor drain resist corrosive liquids found in chemical laboratories, dairies, breweries, and atomic energy and bottling plants while maintaining high sanitation standards. It has a loose set, non-tilt grate that withstands heavy traffic. CF8 Stainless Steel permits machining for threaded outlets, tops, flashing clamps, plugs, and strainers that are offered as options with this drain. (Note: This drain is engineered for use in areas where wastewater is free of sediment or debris and a shallow body is required.)
