Sash Lock ID

It's hard to tell for sure what you have without knowing your dimensions, but our 90-005 is similar. You'll have to compare your lock to the pictures and information we have on our store page to confirm.

Another important detail is the style of the tongue. It's hidden in your photo, but of all the locks you linked to, the style of tongue is the main differing factor. You should remove your lock from the window to confirm if the 90-005 is a match.
