Pella 750 Series Glass Door

Question

Looking for the correct part number for a mortise lock mechanism for a Pella 750 series slide glass door. Is it 82-247? I can't believe this part is almost $200 but I want to make sure I buy the right part. Please advise.

Thanks for reaching out! It does appear that this is the correct replacement based on other posts I've seen from other customers. However, to confirm for sure that this is the replacement you'll need, you will need to remove the mortise lock from the door and compare the dimensions from the diagram below.
