Sliding glass door hardware
Your handle is similar in design to our 82-036, but you need to check the hole spacing and method by which it locks to verify that it's the same design as your original. If they differ in any way, let me know.
You also mentioned rollers, but I don't see them in your photos. This service requires a clear and unobstructed picture of all parts you want to remove. In the case of rollers, that means you need to take them out before we can identify. Make sure to take detailed and precise dimensions, too, as you will need them for comparison later.
The stickers don't tell us anything about what hardware is used on the door. This is a photo identification service, so we need a clear and unobstructed photo of each part you want to replace before we can make a recommendation. If you can't supply those photos, we can't help.
There's not, unfortunately. Patio door records are slim at best, and many manufacturers don't have public records of precisely what parts are used on what doors (if such records were even kept at all). For older doors like this you'd be lucky if the company that made it is still in business. There's a ton of turnaround in this industry.
That's the main reason we provide this service. In most cases, the only way to identify hardware is to use the old parts as a reference. This is a routine and necessary part of this kind of project. There are no easy shortcuts.
