Thanks for posting! Your mortise lock looks like it could be either our 82-211 or our 82-214B. To determine which of these is the best possible replacement, you'll need to carefully review and compare the dimensions to your existing mortise lock. Take a look and see what you think.

Here are the dimensions for part 82-211.
