Pella
Thanks for your patience during this busy season. Your keeper appears to match our 90-331. Just make sure to review all other dimensions to ensure that they line up.
Thanks for clarifying. There are actually many different locks compatible with this keeper, there's not just one. You could have anything.
It's not possible to identify locks by just the keeper. It would be better to see a clearer photo of the lock itself. I need to see it from a top-down, unobstructed angle. I also need you to measure the distance between the two installation holes, center-to-center, and write that out in your response for me to review.
Thanks! Please see our 90-278. This appears to be a good match for your original lock. It comes with a keeper, but since your original is a different style you can just discard that.
