A cathode ray tube includes an evacuated envelope having a substantially rectangular faceplate panel with two diagonal axes that extend between the opposing corners of the panel. The panel includes a mask-frame assembly having a frame with two opposing long sides and two opposing short sides forming a continuous mask support frame. The frame is mounted within the tube by brackets located near the corners of the frame. Each bracket is adjustably secured along the short sides of the frame and includes a flat surface section extending normal to the diagonal axes of the panel. A spring clip assembly is secured to the flat surface section of the bracket for engaging a stud affixed to the panel.
