Measuring for Alenco window lock

A handy person from texas says:
I have some window locks that have broken, the builder said they were alenco windows and it looks like they are made of aluminun. How do you measure the lock?

Thanks for posting! The key measurement for window sash locks are the screw holes centers. Knowing the distance between the screw hole centers as well as the screw hole center offset from the back of the lock, are both important to know. I'd be happy to help you identify what you need, but I'd like to see a picture of your lock in addition to dimensions. You might also want to look at our 90-005 in the meantime.
