This is a great question. The 39-107FK fits Truth Hardware's EntryGard series operators. The 39-375 fits Truth Hardware's Encore series operators. They are not interchangeable. What operator do you currently have? If you cannot match it up to one on our site please post a few photos for us to see. We would be happy to research it for you. |
