Russ: If you still have your installation sheet, it will tell you the manufacturer of the sliding glass door. Google the manufacturer adding "parts". You can also enter "sliding glass door handles" and then where there are a group of handles shown, click on the blue title above and you will see many different handles shown. Search the pages and when you see your handle illustrated, click on it and then when it comes up, click on websight. It will show the manufacturer and how to order.a replacement. It appears that two long Phillip head screws are holding the handle in place. Removing the two screws will allow you to remove the broken handle and replace it with the new one. GOOD LUCK!
