Help identifying correct window latch, 2-3/4" long

This looks very similar to our 26-266, though ours is only 2-3/8" long, not 2-3/4". Can you confirm that dimension?

We also have the 26-408, which is 2-13/16" long, but it looks a little different. I would recommend removing your latch from the window, then carefully comparing your measurements to those we show for both products. That will confirm it.
