The actual traverse rod is a motorized unit from BTX. See my review on the home page. The dark rectangular looking surface behind the decorative iron cornice is a bronze fascia from Iron Art by Orion that covers the aluminum motorized hardware. Click on http://www.ironartbyorion.com/tuscany.asp?catid=19 for some of their products.
The decorative wrought iron grillwork was custom made by an artisan in the San Diego area. If you live in the area I can provide the name of the artisan, if not I would recommend that you show the photo to a welding shop in your area and perhaps they could fabricate something similar. Thanks for your question. I this does not provide the answers you need please reply and I will try to be more specific.
