The Watts RD-970 is a perforated stainless-steel ballast guard designed for use with compatible roof drain systems. It surrounds and protects the drain dome by preventing ballast, gravel, and debris from entering the drain while still allowing high-capacity water flow. Its corrosion-resistant stainless-steel construction makes it suitable for long-term rooftop exposure, particularly on ballasted roof systems.
