Broken lock
Hello! This lock looks like a match for our 38-144 at first glance. Review our dimensions below to verify. As for whether this is an easy fix, I personally think it's doable. These just screw to the frame, there's nothing fancy to it.
The only complication that might arise is that the new lock might not be compatible with the old keeper; these are the hooks on the window frame that the lock secures to. You should check to make sure that your keepers match our 38-276 and 38-277. If they do, then you're good to go!
Awesome, thanks for the purchase! We really appreciate it.
Best of luck with the rest of your project, and please feel free to reach out if you needed anything else!
