need a door latch.

Thanks for writing in. We don't carry the exact face plate your mortise lock works with, but you may be able to reuse it with a replacement lock. For the lock, take a look at our 82-218. This looks right, but compare the dimensions listed below with your old old lock and let me know if you think this matches what you have.
