Door Lock
Hello, thank you for posting,
If you are only in need of a new locking lever, please review the style and dimensions of the 82-107 lever kit. For a full new handle set, start by reviewing the dimensions of the 82-089 that has a 3-15/16" installation spacing from center to center.
If the locking lever is breaking, I would recommend also checking to make sure the internal lock is working as well. With the handle set removed, you can insert a slotted screw driver into the lock key way to make sure you can throw the latch. If a new mortise lock is needed, please provide images of the original to move forward.
Please review and let me know if you have any questions!
