The Watts FS-850 is a 16-inch square by 12-inch deep flanged sanitary floor sink designed for commercial environments with high drainage demands. It features a white acid-resistant porcelain-enameled cast iron interior, a loose-set porcelain-enameled cast iron grate, an aluminum dome bottom strainer (or polypropylene version depending on model), and a no-hub outlet — making it suitable for either direct or indirect waste systems in non-traffic areas.
