Hi It looks like the dimensions are 1 3/8 (or 1 13/32) by 1 1/4. I don't know the brand of window or screens. What do you recommend? Thank you very much.

It's tough to say. We don't have this exact butterfly latch, but we have two that are similar and also measure 1-1/4" tall. See our 90-227 and 70-172. Could you possibly use either of these?
