Cannot find part

Hello there. We don't have an exact match for this tilt latch. I want you to start by comparing to our 26-243 and 26-244. The fact your old latches have a circular surface doesn't trouble me; that won't matter so long as the latch body fits the window. Review the dimensions below, particularly of the locking tab on the underbelly of the latch, and let me know how anything differs from your old latch's measurements. This will help us clue in on a better option if we can find it. Many thanks.
