A printed wiring assembly card insertion/extraction tool is provided of circular cross-section with a cam-like member at one end. Each card within the card cage has a tab centrally located along one edge, the tab containing a keyhole-like aperture. When the cards are in their normal side-by-side position within the card cage, all of the apertures line up with a similarly shaped aperture in a support bracket mounted on one side of the card cage, such that the insertion/extraction tool may be inserted through the apertures. A selected card may be extracted by appropriate rotation of the tool about its axis, whereby the cam-like member engages the corresponding aperture of the selected card and forces it out. Likewise, cards may be inserted by reversal of the process. A retaining bracket is provided on the opposite side of the card cage opening from the support bracket.
