The Watts RD-300-CP15 is a promenade-style roof drain designed for use in paver decks, terraces, and walkway areas where a traffic-rated, low-profile drain is required. Its epoxy-coated cast iron body provides long-term corrosion resistance, while the ductile-iron square top delivers a stable, heel-proof surface suitable for pedestrian traffic. A flashing clamp with an integral gravel stop ensures secure waterproofing membrane integration, and the drain is supplied with a standard no-hub outlet for straightforward installation.
