TPO Clad Stainless Steel Bottom Outlet Roof Drain with seamless flashing and drain basin. Heat weld TPO membrane directly to the drain flashing. Comes with strong ABS Cyclolac dome strainer. 2", 3", 4", and 6" sizes available.
Note on Fittings: Two types of fittings are available. A threaded adapter fitting is used primarily with 2" PVC pipe applications. The threads on the bronze fittings are male and can be attached to a threaded female PVC adapter. A no hub fitting is the standard fitting used in the industry. With this fitting a rubber coupling is used to connect the drain to the drainage pipe.
I've been using this manufacturer's drains for years. The stainless steel iteration of the TPO coated drain is the best yet. The ability to weld directly to the flange eliminates the need for a clamping ring. Clamping rings cause ponding.
Great TPO Roof Drain
We were looking for a drain that we could weld directly to our TPO roofing membrane. This drain did the job perfectly.
