Interior sliding glass patio door latch?

Hey, Matt. It looks like you have an older style handle set. We may be able to supply this thumb lever by itself, but we still need to look into whether or not it's still available. Please bear with us a little longer.

Thank you for your continued patience with us. I am afraid we do not carry a replacement latch exactly like yours. I would suggest replacing your handle set. Have a look and consider our 82-020 or 82-033. I believe either one should work on your door. Look over the measurements of both pieces and see what you think.
