Screen pulls in corner to take out screens

I'm afraid I can't determine what screen corner you need based on this photo. We offer a wide variety of different corners, which you can see here, and many of them have pull tabs built in.

However, there are a lot of details currently obscured in this photo that are necessary for identification. In order to proceed, I need you to remove an undamaged version of this corner from the screen and show me a photo of it by itself. I will also need precise dimensions; starting with the thickness and depth of the screen frame would be ideal.

Please let me know if that's possible and we can work from there.
