Roof Drain and Overflow Drain
Designed to save installation costs and simplify installation, the roof and overflow drains of this unit are attached to a single deck plate. This permits both 8-1/2” drains to be secured to the roof deck from above the roof, eliminates the need for an underdeck clamp, and requires only one roof penetration. The roof drain has a combined flashing clamp and gravel stop. The overflow drain is fitted with a combined flashing clamp and 2” water dam. The pair are constructed of Duco coated cast iron and protected by polyethylene dome strainers.
