Bi-fold door adjustment and repair?

Posted by spedprof (My Page) on

I have a 2 year old bi-fold door that has the usual bottom pin sitting in the 2 inch channel. However, this pin is threaded and adjustable to provide the exact door height needed. What happens, though, is that over a period of weeks or a few months of opening and closing, the door gets lower and eventually slips out of the top channel. I assume the bottom pin is losing just a bit every time it swivels in the channel. If I remove the door, reset the bottom pin, it is fine for a few months.

Is there a way of locking that bottom pin so that it swivels as needed in the bottom channel but only goes back and forth and not get shortened?

Thanks in advance.

With enough door height above the track, you can add a jamb nut on the bottom pin. You could also use a drop of thread-lock, available at auotu parts stores.
