Sliding door latches and catches

Question

I thought maybe these were Anderson sliding doors, but couldn't find any markings. I need 3 sets of these if you can help.

Thank you for reaching out to us. The Andersen mortise lock and keeper you are searching for is product 82-037. Your interior thumb latch was Andersen part 82-039. However, that has now been replaced with 82-043. Please take a look at those products and let us know how that works out for you.
