looking to replace all the handles
Thanks for posting. These types of Patio door handles only come with the recessed outside handle, I'm afraid. It is made this way as to not interfere with the sliding screen door. You could attempt to install something like our 82-044 above or below the existing handle, but it would not be incorporated with the existing handle setup. If you attempted this, you would want to take great care not to drill too deep, or you'll risk damaging the glass or the door. Let me know if you have any other questions.
You would have to drill holes and then mount the handle set with screws appropriate to your door; a local hardware store might be able to assist with that. Again, we stress that if you try this, take great care not to hit the glass while drilling.
What would you suggest using as a backplate or mechanism to anchor the inside for 82-044
If you were to use the 82-044 pull handle all you would need to do is to drill a hole through the door style all the way to the inside of the door. You would need to use two pan head screws with a 10-24 thread count. You would need to purchase the correct length of screw from a hardware store in your area. Take the handle to the store with you to get the correct thread count and length. You should not need anything else to install the handle. However take care you don't damage the door or drill into the glass when installing the handle. One idea would be to remove your existing handle to take a peak inside the door style to see if you can drill through it.
Unfortunately, I don't know of any company that might sell this exact hardware setup. It is fairly old fashioned so there is a good chance that it's not made anymore. At the very least, the only thing I can say with confidence is that we don't sell an exact match.
I'm very sorry for the inconvenience.
