Window Lock

Hi, Tony.

We sell many locks that may potentially replace this but we'll need more information to narrow down your options. Can you write out the distance between the two installation holes, measured from center to center? It would also help to know the backset, which is measured from the center of the installation hole to the top edge of the lock. You can use the image below as a reference where the backset is 7/16".

Thanks for getting back to me! Our 90-278 appears to be our closest match with 2-1/16" hole center spacing but the backset is 11/16". Look this part over and see if you think this could work for you.
