Thanks for posting! It is likely that you might need to replace the entire handle set as we do not sell the latch separately. We actually did sell this type of thumb latch at one time, but they've been discontinued for years. Also, our 82-243 does look like it could work as a replacement, however, we'll need to see a photo of your handle set to confirm. We'd be happy to take a look. |
Does this help?
That last pic of another of their doors looks like it is installed upside down but I haven't messed with it yet. The client said it's never really worked properly.
