Lock and keeper for windows.

I see you purchased our 90-278 lock set. I know the keeper isn't a match, but did the lock itself work? If so, hold onto it. The keeper you need is most likely sold separately, but as long as the lock fits then you should be fine using that.

See our 90-237 keeper in the meantime. This is just an educated guess, but let me know how well it compares to your original.

There are tons of locks that work with the 90-237. The lock that comes with the 90-278 set is one of them, which is why you want to hold onto it. Assuming that the 90-237 is a match for your keeper then the two products will be fully compatible.
