The roof drain has a combined flashing clamp and gravel stop. The overflow drain is fitted with a combined flashing clamp and 2” water dam. Both are constructed of Duco coated cast iron and are protected by polyethylene dome strainers.
Figure 1831 offers high profile cast iron domes the assembly is mounted on compact 19″ x 10-1/2″ mounting plate.
