Nylon flange bushing

A home owner from Fort Myers FL says:
Bushing used as a glide in upper track for my bi-fold doors. Manufacturer unknown.

ID is 1/4 inch, OD is 3/8 inch. Length is 5/16 inch.
Flange OD is 5/8 inch.
Flange thickness about 1/32 inch.

Most critical measurement is ID and flange OD.

Hi there. We've related a couple of bushings on this page. See the 21-150 and 21-163. If it's a guide, however, you might want to consider 21-174, as the pin will not bypass this one.
