The white disc that's attached to the pin on top of the bi-fold door of the closet is missing. I went to Lowes, but I could not find the exact disc. They do sell a little kit of 2 discs and 2 metal pins which look much bulkier and thicker than the one I am trying to fix. Is there any part like it I can easily find to replace it?
Also, the the rest of the normal working discs which are not missing look like permanently fixed. It does not seem that I could just get a disc and put it on top of the pin. How does it work? Do I need to pull the pin out of the door and attach the disc permanently to the pin and then dowel in the pin? Thanks
