I am looking for replacement sliding glass door handles like the one in the photo. Please let me know what measurements you would need to determine this product.

Hello, thank you for posting! 

Take a look and review the dimensions of the 82-080 handle set that has a 4-15/16" installation hole pattern. Please let us know what you think and if you have any questions.

Thank you, that is a match. Can you also help me understand what the locking mechanism is. It appears to be a double mortise lock but it also has top and bottom strike plates as pictured. Thank you
Casey

Hi Casey, 

Please start by reviewing the dimensions of the 82-268B mortise lock that is compatible with the 89-042 strike plate. I was not able to view your original strike plate in the pictures submitted. Let me know if you have any questions.
