ABSTRACT:
A cathode-ray tube shadow mask mounting system that allows the mask to be removed from the faceplate and replaced in exactly the same position as it occupied before removal includes screw-receiving inserts permanently embedded in the inner surface of the faceplate outside the viewing area of the display screen. Tubular screw guides are secured to the shadow mask frame in corresponding positions, the guides and the inserts having complementary beveled surfaces for drawing them into alignment when a screw is inserted through the guide and threaded into the insert.
