This is a set of two NEW washers for the black and tan Featherweight bed extensions. Use one for each side of your bed extension. When installing the washers first place a cupped washer on the screw followed by the flat washer. (Screw is not included.)
These washers are only necessary for Featherweights that were originally black or tan. White Featherweight bed extensions are held on with pins and do not require a screw.
