I too have a Daryl Patiorama sliding glass door in my home. My husband will not replace the old thing. We have four children and the door opens and closes more times than I can count on a daily basis. Since the over use of the door and my husband's unwillingness to replace, the door is in need of replacement parts. I was put in charge to find the parts. But, no fear... I FOUND THEM!!! You can too at www.glassdistributorsinc.com
Good luck to you all. Let's hope that someday I will have a new sliding glass door.
