A three point support for a shadow mask screen within the faceplate panel of a color cathode ray tube is provided by three studs embedded in the glass side walls of the panel and spring mounting members which are connected to the studs and to edge bonded bimetallic strips which in turn are connected to the shadow mask. The springs and bimetallic strips are of dissimilar metals, and each spring has a cross-sectional area substantially less than the cross-sectional area of each bimetallic strip thereby thermally insulating the bimetallic strip from the stud of the faceplate panel.
