tilt latch sets

Hello! Thanks for reaching out to us. I'm afraid I can't make out what you have from this photo. Your tape measure is actually obscuring too much of the latch for me to be able to ID it. Can you show me a clearer photo of the latch by itself? Seeing it from the top and sides would be the most helpful.  I can then check our inventory to see if we have a match.

Your tape measure is still obscuring most of the latch. I cannot see the top of the part, which is one of the most important details. 

For now, my tentative suggestion is the 26-393. Review its specs and see how well they compare.
