Searching for Simonton patio door locking gear D30069-105

Hello,

Unfortunately, this piece isn't available by itself. You'll most likely need a new thumb turn and maybe even a new handle set. We can help but we'll need to see more of the related parts such as the handle set, thumb turn, and mortise lock to research your replacement options. Thank you!

Thank you for sending over the additional photos. There's a chance that we may be able to provide a replacement for your handle set but we would need to see your assembly to confirm, which is missing from your new batch of photos. The more information that we have, the more confident we will be in our recommendation. Thank you.
