Benchmark bifold closet door pin

I don't recognize this cap as a Benchmark product. I do remember Benchmark using either our 21-043 or 21-044 guide pins around thirty years ago, though they don't look like yours. May I see the track and the other door pins? No need to take the pins out of the door, you can just show them in the back of the door. Once I see the related hardware I may be able to work something out.

Thank you. I do not think this is a Benchmark track. I think we can still help, though. Look at our 21-404 track, 21-044 guide pins and 21-002 bottom adjusting pin. Do you think you could use this hardware?
