Sliding glass door keeper replacement

A landlord from Honolulu says:
Hi, I am a landlord and my tenant told me that the sliding door keeper in the unit she is renting broke. As you can see in the photo, there is a chip on the bottom left of the center piece. I have tried to look for a replacement in various hardware stores in Hawaii, but none of them carry the part that I need. I was wondering if you folks happen to have it or something similar that will fit on the frame. Thank you for your help in advance!

Hello there!

Thank you for reaching out to us. I'm afraid we don't sell an exact match for this keeper. Would it be possible to see a photo of the mortise lock that this part interacts with? Hopefully, that'll help narrow down some options!
