The frame has two substantially perpendicular flanges, a first flange and a second flange. The first flange extends from the second flange away from the screen of the tube. The second flange extends from the first flange toward the shadow mask. The second flange includes peripherally spaced tabs extending therefrom. The shadow mask is telescoped into the frame and is attached to the tabs. In a preferred embodiment, the corners of the frame are truncated.
