A shadow mask assembly for a cathode-ray tube. The shadow mask assembly includes a taut shadow mask membrane affixed to one edge of a closed frame. The frame is angled inwardly from the edge for increased resistance to buckling. Mounting clips generally aligned with the tube axis are secured to the frame inwardly of the outer edge and project outwardly thereof into engagement with locating holes in the envelope. The clips are deflected inwardly behind the outer edge for disengagement and to permit assembly of the shadow mask into an envelope having an inside dimension close to the outside dimension of the frame. |
