The burner housing appears to be an OEM Golden Blount part. Heavy duty stainless steel; well-made with all the attachment screw receivers positioned exactly where they had to be.
Shipment was prompt and at no charge. The parts are expensive but then again so is the Sizzler II grill they are made for. The important thing is that the grill is now built-in but I can maintain it like new for as long as I need. Good folks. Good parts. Good service.
