One-piece spun aluminum body and heavy duty cast aluminum strainer dome and clamping ring provide strength and durability. The drain flange has a depressed sump area to facilitate water drainage from the roof surface. The TRI-BUILT® Aluminum RetroFit Roof Drain incorporates the technology for a mechanical watertight connection to PVC or cast iron pipes to prevent water from backup damage. Available in 3", 4", 5" and 6" sizes. Available with TPO or PVC coated flange for direct membrane attachment or copper stem and flange for more corrosive environments.
