Pins

A home owner from Kentucky says:
The line that move in the track have no springs. I have tried tightening the screw below it but the pin keeps popping out of the track. Will replacement hardware keep the doors from popping out? Any help
Is greatly appreciated

Thanks for posting. I think we should be able to help, but I need the diameter of those pins as well as the diameter of any caps atop the pins. If there's a sticker that shows the brand or manufacturing information, that also would be most helpful. Many thanks. You can read more about repairing Bifold Doors here.

The cap on the pin is approximately a .370 diameter. The pin itself is approximately a .308-.310. I could not locate a model number or a manufacturer.

Looks like you have the old model of the Slimfold bi-fold door. They have made a simple improvement to help keep the doors on the track. Your bottom threaded pivot pin, the 21-001, looks fine. You will need to replace the other three with the 21-007 spring loaded guide pins. See our video below on installation. Note that you will not need to use the 21-154 pivot rod clamp on these three spring pins, just on the bottom pivot pin.
