Folding closet door guide on tracks

I'm afraid this pin with the 1/2" nylon cap is no longer available. That said, we do have a few suggestions that you can consider. Start with our 21-101, 21-103, and 21-109. Also take a look at the 23-115 pin. See if you can use any of the caps listed; some are a little large and some are a little smaller in diameter, but we cannot find anything closer. The only other option would be to use a complete new track kit like the 23-505.
