Hello there!

Thank you for reaching out to us. I'm afraid this sticker doesn't tell us what locks your window uses. Can you show us some photos of the lock you're looking to replace? We'd also like you to write out the distance between the two installation holes, measured from center to center.

They are 2" center to center
What brand are these can you tell from the photos and model number given before on first email?

I'm afraid the information you gave in your initial post doesn't tell us the manufacturer of the window. We don't sell a match for this lock with 2" hole center spacing, unfortunately. In terms of design, the 90-077C and 90-161 are similar but they measure 2-1/16" on the installation hole centers. You can always triple-check your dimensions just to play it safe!
