Window lock, 3/8" from back of plate to inside of hook

Thanks for reaching out to us. We might be able to help with this. However, the details of the lock are obscured when installed so I'm not sure. Can you remove it from the window and show us a few photos?

Thank you! Check out the 38-001 and 38-078. One of these may be what you need. Review the specifications and see if one of them matches what you're searching for.
