Abstract
A covering for a discontinuity in a mask support frame for a tension mask cathode ray tube comprises a stiff yet flexible (or bendable) metal strip having a first surface for facing a mask frame surface which is proximal to a phosphor screen, and attachment to the mask frame on at least one side of the discontinuity, and a second surface facing the phosphor screen. A portion of the covering may be formed to match the cross-section profile of the mask frame surface to which it is attached. The covering may be formed in a continuous rectangle to form a rectangular frame assembly capable of attachment to a faceplate.
