The CF8 rough finish stainless steel (equivalent to type 304) bodies and loose set non-tilt grates in our 9713 and 9718 Medium Duty Top Floor Drains resist corrosive liquids found in chemical laboratories, dairies, breweries, and atomic energy and bottling plants while helping to maintain high levels of sanitation. CF8 Stainless Steel also accommodates machining for threaded outlets, tops, flashing clamps, plugs, and strainers that are offered as options with these drains. (Note: These drains are engineered for use in areas where wastewater is free of sediment or debris and where a shallow body is required.)
