Abstract
Abstract A printed wiring board assembly including a printed wiring board including a pair of guide runners attached to an upper and a lower edge thereof. The guide runners include an elongated body, a pair of elongated walls extending the length of and from one side of the body, and a groove formed the length of and on a second opposite side of the body. Projections extend from one of the elongated walls through apertures in the printed wiring board to retain the guide runners in engagement with the board. Protrusions extend into the groove and engage depressions in guide tracks of an associated printed wiring board file to lock the board assembly in its fully inserted position within the file.
