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.
We were looking for a drain that we could weld directly to our TPO roofing membrane. This drain did the job perfectly.
