HI,
Not sure how old these windows are but both sash are broke. I had purchased 90-300 which looks very similar but the piece that goes between frame is too wide. I don't have a good pic of what it latches onto the window. If you need more info I can get it. Appreciate any help you have. Thanks, Mary
Hi, Mary.
I agree that our 90-300 lock is similar but its hole backset is off from yours so it won't work regardless of the keeper style.
I believe your lock's backset is 11/16". If I'm right, then the only two locks we sell that will replace this is the 90-274 (2-1/4" hole center spacing) and 90-278 (2-1/16" hole center spacing). You'll need to verify the hole center spacing on your old lock to determine which is the best match.
We'd be happy to help with the keeper but we would need to see a clear photo of what you have. Detailed measurements, as well as the hole center spacing, are also a huge help.
The backset is actually the measurement from the center of the installation hole to the top edge of the lock. The image below shows what I mean. The 11/16" measurement would be the backset on this lock. My apologies, I should've been more clear!
Dimensions for 90-278
As for the keeper, I recommend taking a look at our 90-257. Look over the dimensions and compare them with your old one to see how they match up.
My pleasure. Let me know if I can be of further assistance and best of luck with your repair!
