These corrosion resistant, Duco coated cast iron scupper drains are available in several configurations. The 90 deg side outlet design installs at the junction of roof and parapet (sidewall) where the drain's threaded outlet attaches to an outside downspout through an adaptor (Fig. 1550). The 45 deg threaded outlet design is for connecting the drain to an inside leader and can be offset into a wall. Both angled and flush (to prevent trip hazard) grates are offered and are loose set into the drain body.
