The Watts RD-280-SO is a promenade deck drain with a side-outlet configuration, designed for terraces, walkways, and paver deck areas where a traffic-rated, low-profile drain is required. Its epoxy-coated cast iron body offers long-term corrosion resistance, while the ductile-iron square top provides a stable, heel-proof surface for pedestrian zones. The side outlet allows horizontal piping where vertical drops are not possible, and a flashing clamp ensures proper integration with the waterproofing membrane.
