I am in need of a replacement lock for my restroom window. Included in these photos are a pic of my window, and the actual lock from an exact window in my house.
Good morning and thank you for posting and submitting your pictures to us.
Now, just from taking a look at your lock and keeper, it appears the Swisco 90-025 and 90-108 may be the best match. However, be sure you measure the distance between screw holes on both your lock and keeper.
You'll notice the 90-025 Window Lock, measures 7/8" on installation hole centers and the 90-108 measures 11/16". Take a look at your original and compare it to the ones I suggested.
