Window lock
Greetings! Just from your photo, I think our 90-313 looks similar. You'll have to look over the dimensions and compare it to yours to be sure. Let us know if you think it could work for you!
The most important measurement is the distance between the screw-holes. The measurements were available through the link I sent you, but here you go!
I actually don't think that lock will work for you even if it had a flat sweep. I think Kathleen mistook your flat sweep for the throw and thought the broken piece on the other side was a hook. Now that you mention that your sweep is flat instead of a hook, I see that we had it reversed.
With that in mind, you'll note that the holes on our 90-313 are offset closer to the throw, while the holes on yours are offset closer to the sweep. Because of this, there's no way the 90-313 is going to work in your window. You just wouldn't have the room to install it if you use the same holes.
I'm afraid we haven't been able to find any lock that has the same hole placement as yours. All of our locks either have centered holes, or holes offset closer to the throw, like our 90-313. I haven't been able to dig up any lock that works differently. I'm afraid we won't be able to offer a replacement for you at this time.
Now, note that I said you won't be able to use the same holes. If you were able to redrill your holes, then the 90-313 is back on the table as an option. I cannot guarantee it will work, but it is likely going to be your best bet. If we're just looking at the style of the sweep, I think a hook will work the same way as a flat sweep.
Hopefully this all makes sense. Let me know if you have any questions.
Rick
