Searching for why bi-fold doors pop open

Question

After replacing the Nylon bushings, pivot pins, and springs on all four doors, one pair won't stay shut and pops open. The doors close without interference.

What do I need to adjust?

Thank you,

Juan

Hello,

If the doors are squared up and open properly, one possibility is that the 21-275 bumper in the top and bottom tracks between the doors could be too long. You could try gradually cutting the bumpers down by 1/4" and testing the doors until they stay closed. Thanks for posting.
