Area of Application

Used in IRMA flat roof construction (inverted roof membrane assembly). The dome provides sufficient free area for quick drainage of rain water through the deep sump body and protects the drain and connected piping from the intrusion of debris. The Flashing clamp holds flashing and roofing materials securely to the drain body. The perforated stainless steel gravel guard is supplied to retain the crushed gravel used in IRMA flat roof construction.
