Replacement part # and lead time

Thanks for posting. For your vinyl patio door track, you can use a track cover like our 80-102. I'm not sure about the roller, unfortunately. The 81-018 sliding patio door roller is used by many vinyl door companies, but there's no telling for sure what you have. The only way to know is to remove yours from the door and see how it compares. You likely won't find a stamp or number anywhere on the door that tells you what roller you have. Most manufacturers don't design doors with roller replacement in mind, unfortunately.
