Bi Fold door part

I own several condos in a condo complex that all have metal bi-fold closet doors. Many of the guide rods are missing at the top and bottom. I'd like to replace all the ones that are missing and purchase a few more to keep if anymore should go missing. I'm not sure which rods for either the top or bottom are the correct ones as it appears that the previous owners throughout the years have changed many of them out which all appear to be different. I have some with springs around the shaft and some without, some shafts are shorter than others. All shafts however do mic out to .325 of an inch. Most appear to be about 6 inches long. They run through about two and a half inches of frame work that contains a plastic clip with a screw. The condos were built in 1968 if that helps. I could send you folks a picture of the doors if need be. What can you tell me?

The rods ranged from 5-1/4" to 6-1/2"

All their shafts diameters measure .325 of an inch which is between 5/16ths and 21/64ths of an inch.

Some have springs and others do not.

Many thanks for your correspondence. I believe we can help, but we need more information. Can you show us the back of the bifold door, where the pins fit into? That should help us determine the manufacturer, and will help us narrow down the possible options. Any manufacturing label on the door would be a help to see as well. We shall do our best to identify the parts needed from there. Many thanks.

Paul, I just found a tag on the inside of the doors that reads, Welowood United States Plywood Corp. 777-3rd ave. New York (Door Department).

Thanks again for getting back to us. What you're showing here is the original Slimfold door whose pins have been replaced with a newer style. My first recommendation will be one 21-001 bottom adjusting pin; based on your photos, you can reuse the old pivot clamp after you make the adjustment on 21-001 pin. I also recommend three 21-007 spring loaded pins; one for the top pivot and the other two for the top and bottom guide pins. No rod clamps are needed for these. Lastly, I pulled up a list of other accessories you might need for your rehab job and some media guides for further explanation. You can find these listed on this page.
