Lock for vinyl sliding window

Hello!

Before I recommend anything, can you write out the distance between the two installation holes, measured from center to center?

Thank you! 

Emily isn't here today, but I will do my best to help you moving forward.

The bad news is that we don't have a sweep lock with that hole spacing. Can you confirm that for me? Make sure to only measure from the center of each hole, not their edges.

The closest option we seem to have is our 90-161, which has a 2-1/16" hole center spacing and a 7/16" offset. Would this work for you?
