Doors are 49 years old and the pin pictured is for the bottom front (the part of the door that moves. It is held in place by a screw. I believe the problem is the broken plastic piece on the bottom.

We sell a ton of bifold door pins that are similar in design to what you show here. Before I recommend anything, can you tell me the diameter of the pin itself? Can you also tell me the diameter of the top part of the nylon cap?

The diameter of the pin is 5/16 inches or .3125 inches. The diameter of the top part of the palstic cap is 1/2 inches. The lenth of the pin is 5.25 inches.

Thank you! 1/2" is very, very big. I think you may be measuring the wrong part of it. I only need the top tip, not the "brim," so to speak.

Right now my top contender is the 21-016. The shaft is 5/16" in diameter but the top tip, which goes into the track, is 13/32". Look this over for now and see what you think.
