93' metal bi-fold door that needs the pins/guides replaced

A handy person from Chicago says:
A little job I'm doing for someone that has 3 closets. One 5' wide, one 4' wide and one 149" wide, all 93" tall.
Will replace all hardware and track. They have a beat up wooden track that I'll do with maple or some other hardwood.
Would you suggest a metal track? I don't know the manufacturer of these doors (to old). Any help would be greatly appreciated.

Thanks for posting. We have metal tracks that should work with your metal doors such as our 21-404 for the 4' opening and 21-402 for the 5' opening. The 149" opening is going to be a problem since the longest is 6' and piecing two together will only give you 144". You would need a bottom and top track for each opening as well as one of our 21-001 bottom pivot pin and three of our 21-007 guide pins for each panel. Additionally, you may need some of our 21-151 nylinders so the pins can slide easily in the door frame. You will need two of our 21-277 rubber bumpers for the top and bottom where the doors meet in the middle. Personally, I would recommend you doing one set to see how it works out for you.
