Sash lock dimension 2 1/8 inch window made by better bilt

Thanks for reaching out to us! The parts you are searching for are the corner mount tilt latches for your sash. I believe the 26-351 Better-Bilt Window Latch should work to replace them but you'll need to carefully look over the dimensions and compare them to confirm.

These are sold as a pair.
