Tilt latch

Thanks for posting! Your tilt latch reminds me of our 26-243 Tilt Window Latch and its opposite handed version 26-244. To confirm that these are the correct replacement, you'll want to find an undamaged latch and compare the measurements shown on the diagram below. 

If the dimensions are not a match, please let me know your exact latch dimensions, written out.
