Metal screen clip.

The issue is that the part of the clip (bottom of picture) that inserts between the window and frame is quite thin. This is because the space between the window and frame is narrow. All clips I have found are too thick at that point. If you can help, it would be most appreciated. P.S. these are very old windows and I cannot find a brand name on them.

Paul, thank you for the reply. the 70-104 is the clip I just tried and is too thick in the prong that inserts between the window and frame. Attached is a photo of a clip that does work, and you can see that it has a thin profile. Do they make this kind any more?
