Hello,
I don't recognize this sliding window latch at first glance but I'm going to have one of our senior experts take a look and see if they could recommend a replacement for you. We'll reach out as soon as more information is available. In the meantime, I've related a few of our parts on this page that are similar to yours. Thank you!
Hello,
The ABC window manufacturer used a latch like yours at one time but has since transitioned into vinyl windows. Unfortunately, they no longer use the die-cast latch shown in your photos. With that being said, we've related three possible replacements for you to review. Take a look and the specifications shown on our product pages to see if you could adapt one of them to work for your application. Thanks for posting.
