SPECIFICATION:
MIFAB Series R1100-G lacquered cast iron roof drain with anchor flange, cast iron waterproofing membrane clamp ring with integral gravel stop, stainless steel perforated 6" (152) high ballast guard with 1/2" (13) round drainage openings and standard self-locking polyethylene dome strainer with a free area of 43 square inches.
FUNCTION: Used in any type of flat roofs and gutters to control the flow of rain water off of the roof. Slotted weirs reduce the volume of water to the leader. Specify -F1, -F2, or -F3 for one, two or three slots to attain the required limitation of volume. 8" diameter body is ideal for applications with limited space. Dome provides for efficient drainage of rainwater and prevents debris from entering the drain line. Anchor flange and membrane clamp with tongue in groove design provides for secure grip of membrane and roof flashing materials. Flow performance per weir is 5 GPM per inch of water per slot.
