Used as a parapet overflow or at the base of a wall where a concealed leader discharges rainwater to the ground. The nozzle design diverts water away from the building, eliminating wall stains. The wall flange covers a rough opening and serves as an anchor. A downspout nozzle is also known as a cow’s tongue or a lamb’s tongue.
Note: The pipe (leader) must extend beyond the face of the finished wall in order to install the 1771 downspout nozzle.
