sliding glass door handle replacement

Thanks for reaching out! Your patio glass door handle looks pretty similar to a handle set we carry. However, I'd like to be sure that it is compatible with your existing mortise lock before moving forward with any recommendations.

May I please see a photo of the mortise lock?

Thanks for posting! Your patio door handle set reminds me of our 82-086. Which is compatible with the 82-265. To determine if this are the right fit for your door. Take a look over the dimensions and compare them to your existing hardware.
