    AREA OF APPLICATION

    Used in flat roofs of any construction where a constant height of water is required. Also used as a Secondary Drain (emergency overflow), draining water when the depth of the water on the roof exceeds the standpipe type water dam height. This Drain can be used near to main (Primary) drain. The dome provides sufficient free area for quick drainage of rain water and protects the drain sump and connected piping from the intrusion of debris. The Flashing (V-Shape) clamp holds flashing and roofing materials to the drain body without puncturing.
