Hello, I would recommend starting by comparing the non-handed 38-144 sash lock to yours. We'll include the specifications from our product page below. Note that this lock uses the 38-276 and 38-277-handed keepers depending on the side of the window the hardware installs on. Thank you! Alternate image for 38-144
