I have ordered and received a thumb latch but it is the wrong one - item #82-049.

Any assistance in this matter would be greatly appreciated.

Thank you,

Hey, Thomas. I think you might want to consider our 82-043, instead. The 82-043 is the newer version of your existing thumb latch. Also note, when the thumb latch breaks it can be a sign that the mortise lock needs to be replaced, take a look at SWISCO part number 82-037, Andersen Deadlock Assembly.
