Thanks for writing in, Ben. Sounds like you might need a new keeper. Your mortise latch looks like our 82-268B, which would make me want to recommend our 89-042. That said, you might want to carefully compare your mortise lock to confirm this, because it also could be our 82-238, in which case you'd want our 89-030. Let me know what you find. |
