K/K Screen Corner

Almond

If I send you a sample piece of the screen corner would you be able to help with finding a part?

the widest part at the corner is a half inch thick by a half inch wide and tapers down both ways to about 7/16 x 7/16 it does have a small tab on one side to go into a guide inside the screen frame. Pencil pointing towards this tab in photo.

I need help finding the correct screen corners, I went to the local big box store and purchased those little gray ones. They are absolutely not the size I need nor do they fit any of my screen frames. my house is roughly 35 years old and I'll assume all of these corners are that age ... (cont.)

Need a new screen frame corner for my house window. OD of the metal frame is 7/16". Width of the tab going inside the metal frame is 3/4" and depth is 3/8". Entire length from outside of corner to tip of tab is 2 3/8".
