Bi Fold Door Hardware Set, 2 Packs of Louver Door Hardware, Contains Top and Bottom Pivots, Brackets and Guide Wheel Bi Fold Closet Door Hardware Repair Kit Silvery and White

Was slightly different to my original in that it didn't need the plastic liner at the bottom but worked perfectly better than buying a new door.

The internal wooden bi-fold doors in my home office were not working and I was worried I would have a big expense to replace them. When I took them off, I noticed that the threads on the bottom fitting had "gone" (they have over 10 years of use) and the door was catching on the carpet.I ordered these - next day delivery with Prime - these are very well made - at least as good as the original fittings and I swapped out the ones which were damaged. This included the bottom metal support and the bottom "hinge". When adjusted and fitted back - the doors now work better than they ever did. The lower price I paid for these fittings does not compromise the quality.
