Hello. Can you please help me find a cent latch with the attached measurement for the vent. The total size is 2 inch but the actually vent popout space is 1 3/8. Thank you.

Thanks for posting. This looks a lot like our 26-122. This can fit in a hole 1-29/32" long and 5/16" wide. Does that match the size of your hole? If so, I think it'd be a good place to start.
