Looking for a replacement thumb turn or new handle

Thanks for writing in! The thumb latch for your handle set, specifically in the brass color is not sold separately from our handle sets. We are only able to offer it in white as our 82-107.

With that said, I am confident that we can supply you with a replacement for your existing handle set, I'll just need to see a photo of the entire handle set. I'll also need you to confirm the position of the thumb latch. Is it offset (on the top or bottom of the handle) or centered?

Please let me know if you have any questions.
