Big Daddy RD-800 Single Cut-out Dual Roof Drain
Big Daddy, the single cut-out large capacity RD-800 Series epoxy-coated cast iron dual roof drain/overflow combination, more effectively limits the risk of leakage and roof damage than multiple single roof drain and overflow units. Because its innovative design requires just one cutout, installation is faster, resulting in lower installation costs. The sturdy drain construction reduces the risk of job site issues while ensuring durability. Unlike competitive dual roof drains, the Big Daddy has a low-profile drain body, allowing installations anywhere a standard roof drain can be used. The RD-800-CT provides overflow through the dome.
*Based on independent lab tests conducted November 2018 using 6” standing water and 10” outlet model.
- Up to 1368-gallon-per-minute (GPM) flow rate*
