Patio door lock.




Thanks for writing in! Your patio door latch reminds me of the 82-043 Andersen Tribeca Thumb Latch. To confirm that this is the right replacement, carefully review the dimensions shown below.

This thumb latch is compatible with the 82-037 Andersen Reachout Deadlock Assembly (made for 2-Panel Gliding Doors) or the 82-242 Andersen Reachout Deadlock Assembly (made for (4-Panel Gliding Doors). The difference between these is the doors they are used for and the design of the receiver. Be sure to compare them to determine which of these is the correct replacement.
