Need help identifying broken screen corner




Thanks for reaching out.
To recommend the most accurate replacement, we'll need know the width and thickness of the frame.
It would also really help to see a photo of the corner removed from the window. Although, I understand it may be difficult to remove them.

Measurements are 1/2" 1/2" and 7/8" incase you can't read them.
The holding pin is spring loaded or can be locked by moving clip to F. O is open so clip can spring



We have had this question before. These are Summit window Screens. I don't believe these corners are still available but I've found that the 95-207 could possibly work in the screen frame. You would need to thicken up the "leg" of the corner with tape (or something else) to account for the space.
I also regret to say that we do not have any replacements for the locking pins, however, you may be able to install the 70-009 pull pins.

If these parts do not work as replacement, I'm afraid the only other option would be to make new screens.
