I am replacing some parts on two Cox bi-fold doors, their series number 26T. The white screw bottom pivot, your part number
21-092, has broken on two more doors. I replaced one other a couple years ago. I'd also like to replace the brown spring-loaded guide on the lower leading edge of the door because it's kind of boogered up. I don't see it in your parts catalog. Do you have it? I've attached two photos.The barrel is about 7/16" diameter and about 1 3/8" long to the first face of the flange.
