I'm afraid I'm not sure what keeper you need without seeing the original. Our 40-197 has been known to work for many different Larsen brand locks, though. Look it over and see what you think. |

That doesn't tell me anything new, unfortunately. I can see what kind of mortise you have in your first batch of photos. Our 40-197 keeper is commonly used with this style lock, but without having the original on hand it's not possible to confirm. I'm afraid all I can do is give you my best guess. |
