Plastic sliding glass door handle
Hello there!
Thank you for reaching out to us. We don't sell your exact handle but we might still be able to help. Can you write out the distance between the two installation holes, measured from center to center?
I'm afraid these photos don't tell us anything new. Is the installation hole center spacing 3-15/16"? If it is, you may be able to use the 82-030. Please note, we do not sell dummy handles, which appear to be what you have in your photos. However, the 82-030 can work in that capacity as the included thumb lever is a separate part that can be discarded. At that point, it would simply be an exterior and interior pull handle.
That's correct, you would want to measure as shown below. A dummy handle is a handle or a pair of handles with no latching or locking function. I hope this helps.

It looks like the handle on the left side already uses a mortise lock but we just don't sell the locking dummy handle hardware that you need, unfortunately. Contacting the original manufacturer of the door is your best bet if you can track them down. I really wish we could give you a better answer.
