Hello,

Take a look at our 38-144 casement lock and see how the dimensions compare to yours. This is non-handed, meaning it can work on either the left or right side of your window interchangeably.

Depending on how old your window is, you may also need new keepers. I recommend our 38-276 (left) and 38-277 (right) keepers. Thank you!
