Scupper / Parapet Roof Drain
FD-4020 series of parapet roof drains consist of a cast iron body with reversible side or bottom outlet, a removable 45 degrees Aluminum or Nickel Bronze grate with 90 degrees combination frame and membrane flashing clamp.
Used at the junction of the roof and the parapet when horizontal or vertical pipes arrangement is used. The sloping grate provides ample drainage and is slotted to prevent debris from entering and blocking the drainage openings. Flashing and membrane are positively secured to the drain body with a compression clamp. This drain can be used as secondary drain or in special cases as primary drain.
