Greetings.. I have two metal bifold doors that are hurting.. the start of the issue is that the wood tracks are fully worn and the pins will not slide. Yes wood, there was no metal in the track. House built in the 70's. Both are 6" wide, 7' 4" tall. Half of the hardware is swapped out for simple bolts.. thanks!! Chris~

Can you tell me the diameter of the pins, as well as the diameter of the cap atop the pins? Also, is there any brand label on the door? From there we'll do our best to ID what you need.

Thanks Bob..
The pivot pin has a diameter of 3/8" with a round plastic guide for a round hole. The pin that goes in the track guide is 3/16". The pin diameter under the spring is 0.32" diameter. The spring is 0.56" OD and 1.9" long.
I could not get any data off of the doors, so do not know the mfg.
I will look for an original guide pin next..
Thanks!!

Greetings. The wood tracks present a problem, but I think we may be able to help. We have a threaded pin, the 21-035 with a 3/16" tip and similar nylon bushings that should fit in your nylon pivot brackets. As for a guide pin, we have the 21-033 with a nylon tip and bushings, and the 21-007 spring loaded pin with a hat type cap and a 5/16" tube. Please review.
