Latch and matching handles
Thanks for posting! Your mortise lock appears to be missing it's faceplate. Can you confirm this? If it has been removed, I'll need to see that part of the lock to ensure we are providing you with the correct part recommendation.
Your handle set resembles the 82-089 Legacy Handle Set; the keyed version is the 82-086. Take a look at the measurement for the installation hole spacing to confirm that this is the replacement you'll need.
Thank you for the picture. We recommend replacing your mortise lock with our 82-265 Multi-Point Mortise Lock with Face Plate. You might also need to replace the keeper with our 82-249, as your current one may not fit the new lock.
Please carefully compare the dimensions below to ensure these parts are compatible with your door.
