Thanks for posting. Are you trying to replace the internal mortise lock, or the turn latch? If so, I would have to see what that looks like removed from the door in order to confirm if the 82-037 would work.

If you are trying to replace the turn latch, please take a look at our 82-043 Andersen Tribeca Thumb Latch and match its dimensions to your hardware. Do you think this would be an applicable replacement?
