Abstract
The invention provides improved strengthening means for the inherently weak corner regions of the framing member of a rectangular color CRT aperture mask-frame assembly. The improved means are in the form of crescent-shaped indentations discretely positioned to add strength to the corner material by substantially following the natural flow of the material thereat. The termini of the crescents are rounded and tapered to minimize stress concentrations in the regions.
