1330-13578-1/2 Inch Diameter Body Roof Drain - Low Profile Dome

The small 8-1/2" (215) diam. body of this versatile roof drain permits installation in flat roofs, gutters and roof valleys where limited space is available. Its flashing clamp securely grips surrounding roofing materials without puncturing them for leakproof performance. This drain is made of corrosion resistant, Duco coated cast iron and topped by a polyethylene dome strainer that keeps drainage systems debris-free for years of service.
