ABSTRACT:
Improved mounting and implosion-protection means and method are disclosed for use in a cathode ray tube having a substantially rectangular glass face panel with a rearwardly extending skirt. A first tension band has a predetermined relatively wide width for compressively inwardly loading the panel at a tension level completely effective to protect against implosion. Four mounting brackets, one at each corner of the panel for mounting the tube, have a rearwardly extending foot. A second tension band substantially narrower than the first band circumscribes and overlays the first band. The second band is tensioned at a level 55 to 78 percent of the tension level of the first band for capturing and compressively holding each bracket foot against the first band. The effect according to the invention is such that the tension level of the second band is effective to retain the mounting brackets, but ineffective to deleteriously interfere with the implosion protective tension exerted on the panel by the first band.
