I have an International Sliding Glass Door (SGD-R20). Don't know the year it was installed. I attached some pics. I need to replace the handle.

Hello! check out our 82-032 patio glass door handle set. This looks like it matches your hardware. If you also need a mortise lock, consider our 82-218.

82-069 should work too, and is a better looking handle IMHO.
