If your pivot pin and guide pins are okay, then see our 21-401 bifold track and 21-277 rubber bumpers. I would recommend one bumper for each track. The nylon pin caps will glide in the track with no problem.
First, install the top and bottom tracks, then place the bottom threaded pin into the pivot block and the guide pin into the bottom track. Swing the door up to the top track, pull down the top pivot pin to clear the track, then lock in the top pivot block. Pull down the top guide pin to clear track and snap it in the track. To square up the door, use the bottom pivot pin by adjusting it up and down. |
