Hi, I'm looking to replace the hardware shown in the attached images. It is Anderson branded, with numbers shown in img_3818. The knob for locking is broken (img_3816), and I haven't been provided with any screws for the lock portion.

Hey there. Check out our 82-037 Andersen Deadlock Assembly. When this deadlock fails, the thumb latches tend to break easily. For a new thumb latch, see our 82-043; this latch comes with installation screws. Let me know if you have any other questions.
