ABSTRACT:
Resilient means on the mask frame of a cathode ray tube support the mask-frame assembly by mating with positioning studs embedded in the sidewall of the tube's viewing panel. To prevent permanent deformation of the resilient support means, mesas are formed adjacent to each means to beneficially limit their flexural movement necessitated by repeated insertion and removal of the mask-frame assembly during tube manufacturing.
