Replace flush mount grip with handles for easier access on both inside and outside sliding door

The project you describe is not possible, unfortunately. Your door is specifically designed to only work with one type of handle set, and that's the 82-002WK. The reason for this is because if you were to remove what you have now, you'd expose a huge rectangular hole that precludes the use of any other style. Short of getting a new door, you don't really have a way around that. 

I am sorry to be the bearer of bad news. That's just how your door is designed to work.

The 88-009 pull will work perfectly well, but it's only designed to work on the interior. These locks cannot take an exterior pull, unfortunately.

The 88-009 actually comes with its own screws. They should be fully compatible with your existing hardware and get the handle working as intended.

Thanks for posting. Alenco Peachtree has been associated with our 81-056 in the past; but the only way to verify if this is what you have is to remove the old rollers and compare to see if they match up. If they do not, please send us pictures of your existing roller, and we'll try and find something better. The video below shows how to remove and replace sliding glass door rollers.
