I currently have Owens Corning Luminess 400/PRO windows, I am not able to find the corner support piece for the aluminum screen locally. See picture below. I would like the part Number and price as I would like to purchase approximately 20 of them if available. Thank you.

I believe the corner key you show in your photos is no longer available. It looks like the corners made by Bayforms who were out of Canada. Take a look at the 95-187 corner key for a 5/16" thick screen frame. See if you could use this one as a replacement. If not check with a local hardware store in your area to see if they may still provide these type of screen corner replacements in their inventory.
