Owen's corning sliding door

Hello, thank you for posting,

Unfortunately we are not able to cross reference the information provided. To further review, we will need to see pictures of your original handle set and mortise lock to confirm the overall style. From there we can get a clearer idea of a potential replacement option. Thank you! 

Thank you for the additional pictures,

Please review the 82-086 handle set that has a 3-15/16" installation hole spacing from center to center. Let us know what you think and if you have any additional questions.
