Most of the doors' plastic parts are broken and therefore get hung on the screw heads in the rails.

Without the plastic parts keeping the sliding pins off the bottom (or top) of the rails, the doors stop a the screw heads in the rails and this keeps them from fully closing. It also makes it very difficult to open the doors.

Besides the label, there's a ink stamp of "Aug 22 1978" on the inside of one of the doors. I purchased the house in July of 2019, but it was built in 1978.

Any chance of matching these parts? There are a total of 5 folding doors in the house. If you think you can match the parts close enough for them to work, I'd like to try one set to see if they work, and if they do, then get them for the other four doors. (Or get them all at once if I can return them for a refund if they don't work out.)

Any chance of a match? Otherwise, I will have to replace all the doors and rails. The (two) doors themselves measure 35 1/2" x 93".

I'm handy enough to remove and replace the parts, and even enough to replace the doors if I have too, so I'm not looking for a contractor, just the parts.

Thanks!

Great news! I ordered two 21-022 guide pins and replaced the damaged ones on the bottom of two troublesome doors, and now both open and close!!

Thank you for your part identifier service!
