Downspout Nozzle
This downspout nozzle is used as a parapet overflow or installs at the base of a wall where a concealed leader discharges rainwater to the ground. Constructed of cast bronze, its nozzle design diverts water away from building, eliminating wall stains. A bronze flange anchors the nozzle to the wall and covers the rough opening.
