Here is a web site that carries something like I am looking for. Problem is, the companies around that carry their product do not have this and I have sent them an email, but to date have not heard back. They are the only ones that I've found with this corner, but I know, from looking at other houses there are other "brands" out there because they have a different look.
Hope this helps in identifying what I'm talking about.
Thanks again for your help.
