Used on flat roofs of any construction other than poured in place where an emergency overflow drain can be used in combination with a primary roof drain. The small diameter drain bodies with low profile domes provide sufficient free area for quick drainage of rainwater while protecting the drain sump and connecting pipe from the intrusion of debris. The external water dam collar on the overflow drain receives water only when the build-up is greater than the collar. The attached dual drain roof deck plate with securing holes enables both drains to be secured to the roof deck from the top of roof reducing the installation time, the number of penetrations and eliminating the need for an underdeck clamp.
