Sliding door from patio.

Hello, thank you for posting! 

Please review our 82-005 handle set as a possible replacement which has a 4-15/16" hole spacing. Your surface mounted keeper has been discontinued and no longer available, so you will need to reuse the one you currently have. Please let me know if you have any questions.
