The Watts RD-980 is a large cast-iron ballast guard designed to protect roof drains on ballasted roofing systems. Its heavy-duty perforated construction keeps gravel, stone, and debris away from the drain dome while still allowing high-volume water flow. The guard surrounds the drain assembly to help maintain consistent drainage performance in demanding rooftop environments.
