Window Venting Lock Replacements

Hello,
I have been looking at the venting lock part number 26-122. Several of my locks are broken, but the opening to insert a new lock is only 1 inch long. Are these adjustable for that opening? Or do you have others that are smaller?
Thanks. I have been looking for these emplacements for years.
