Hi there!

Thank you for reaching out to us. We don't recognize the keeper shown here. Can you show us a photo of the mortise lock? That may help with our search.

It appears that you have an old-style Andersen mortise lock. The old keeper is likely no longer made, but the 89-021 is similar. We don't know if it will be compatible with your lock, but review the specifications and see how they compare with yours.
