Is your 21-022 bi fold door guide pin also for bottom applications? Your description calls it a top pin, but it looks and measures identical to the pins on the bottom of my door. Also, do you have the aluminum track that this pin rolls in. Thanks.
Thank you for posting! If you need to replace the track, then I recommend replacing everything altogether. Check out our 21-404 track, as well as the 21-001 for the threaded pin and the 21-007 for the guide pins.
