Knife latch for 5/8" screen frame

You can take a look at our 70-172, but I'm not sure if they will fit your screens either. You screen and latches might be an older style that is no longer made. If you, can send us some photos of your screen, the latch and a photo showing how they relate to each other. That would help us identify your part and see if it's something that can still be replaced.
