We have 3 mirror wardrobe doors on our bedroom closet and while cleaning the door bottom rollers, we noticed this plastic track guide missing on the middle door.(see photo of roller part and plastic guide) We had to replace the middle door a couple years after it was broken by a teenager. We're assuming when the new door was installed the plastic part was not put on by the installer.
Is this plastic piece available? This is a Stanley/Monarch model.
Thank you.
