Need corner keys for screen frame

A handy person from Farmington NH says:
I have a quantity of extruded aluminum screen frame and the place I bought it from no longer sells it, so I need a new source for corner keys. The photo is a cross section, it measures 5/16" thick by 7/8" wide. The interior measures 3/16" by 1/2". I used to get metal corner keys and would miter the corners, the keys were hidden by done

I'm not sure if we have a match. Check out our 95-013M, 95-054 and 95-129 corner keys and see if you can use any of these. Also take a look at the 95-095 straight cut corner.
A quick learner says:
I think the 95-013M will work, thanks for your help. I had a really hard time sourcing these until I found your store
