Tilt latch

Thanks for reaching out! Your tilt latch lever/actuator looks like it could be either the 26-119 or the 26-234. To confirm which of these is the right replacement, you'll need to carefully remove an undamaged latch and compare the dimensions.

There is a chance that you may need to replace the internal latch as well. If so, I will need to see a photo of that latch removed from the sash. Take a look at the tutorial below as a reference on how to remove the hardware.
