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 water dam height. This Drain can be used near to main (Primary) drain for limited space installations. The small diameter body is particularly adaptable where limited space is available. Flashing clamp holds flashing and roofing materials securely to the drain body.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.
