This round open front, less cover toilet seat is made from commercial-grade, heavy-duty plastic with molded-in color that resists wear, chips, and stains. The STA-TITE Commercial Fastening System reduces installation time and eliminates callbacks for loose seats. The check hinge prevents the seat from going 11 deg (degrees) beyond vertical. The seat is made with non-corrosive 300 series stainless steel posts and pintles and has color-matched bumpers and hinges. It fits all manufacturers' round bowls and is made with environmentally friendly materials and processes.
