Bifold Door Guide Pin

Hi! I have a full vu bifold door that I can’t seem to get back on track. The door isn’t sitting high enough so it drags on the bottom and I can’t seem to things aligned. What parts might you recommend to help get this working again?

We want 2 complete replacement part kits for both top & bottom of mirror door hardware please. Residential homeowner. Thank you.

Hi, I need a pin assembly for a metal bi fold door. I took pictures of the companion door that has the pin installed. I included a measuring tape in the photo. I do not know the name of the door manufacturer. There are no identifying marks on the door.

The track is approximately 3cm wide, the pins that go into the track have slides at stationary pins and rollers at doors that open. Some of the rollers are missing.

These are what I think to be Leigh 70's era bifolds- looking to find similar parts and tracks for identical bifolds in another room (for a 10' opening) which were completely uninstalled and are missing all hardware, including original tracks
