We may have a corner that can replace this, but before I recommend anything I'll need to know the size of the frame itself. Can you tell me its thickness and depth? I can then check our inventory for anything that might be compatible with that size.
Thanks for the additional information. Unfortunately, I'm not sure we can supply you an exact corner to fit your extruded screen frame. I don't believe the corners are still available. My first choice would be the 95-265 corner, however take a look at all the suggested overlap corners to see if you could adapt any of these to your screen frame. My ideas are 95-205, 95-207, and 95-265. You might need to do some trimming for them to fit your frame but if you're handy and don't mind getting creative it should be possible.
Awesome, I'm glad to hear it! Best of luck on the project and please feel free to contact us if you had any follow up questions.
