Replacement tilt latch for window

The closest match that comes to mind is the 26-119 Sash Release Lever. Although, I am not confident that this would be compatible with your existing latch. Carefully look over the dimensions below and compare them.

If they are not a match, I'm happy to determine if there is a replacement solution we can offer. I'll just need to see a photo of the existing latch, removed from the window.
