Bi-functional roof drain from Zurn
The Zurn Froet bi-functional roof drain is a primary and secondary roof drain within one engineered system, eliminating the need for a separate overflow drain, Zurn says. The system includes a 45-degree primary outlet connection, powder-coated finish, corrosion-resistant fasteners and an increased clamping ring surface to reduce the possibility of leak paths. It’s shipped with a standard dome at 5 1/4” in dimensions ranging from 2” to 8”. Low-profile and ultra-low-profile domes are optional.
