According to our records, this series door has used many different kinds of internal mortise lock mechanisms. You could have our 82-218, which seems to be the most popular type, but it may be something different. Carefully compare your existing mortise lock to our 82-218 to confirm that they match. If not, please send some pictures of your hardware for us to review. We will also need detailed dimensions. Thanks!
