Abstract: This invention relates to an apparatus for shock mounting in a frame a cathode ray tube of the type having a rear neck portion containing an electron gun integrally formed with a frustum which terminates in a planar or spherical surface on which information is displayed. Compared to the frustum portion, a relatively narrow first annular member constructed of a substantially rigid material is positioned along the cathode ray tube near the convergence of the frustum portion with the neck. This first ring is affixed solidly to the cathode ray tube and has an outer surface which is formed by two surfaces which form an angle with the cathode ray tube's major axis. As such, a surface is provided for opposing a force directed substantially parallel to major axis.
