Deep Sump Roof Drain
FD-4160EX series of general purpose roof drains consist of a deep sump cast iron body with bottom outlet, a removable cast iron dome strainer, and a membrane flashing clamp with integral gravel stop and adjustable extension sleeve.
Used in flat roofs of any construction. The adjustable extension sleeve permits adjustment, easily accommodating different insulation thicknesses. The threading allows smooth perimeter movement and support of the top at any adjusted elevation. 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.
