Window screen clips

A quick learner from Rising Sun, MD says:
These clips are 3/4 inch markings on clips or windows...I can find no literature on the window manufacturer...we are not original house owner...Can you match these?

thanks in advance

I'm not familiar with the clip you show in your photo, but take a look at our 70-222 slide clip. See if you can adapt that to your window screen.
