Abstract
Three substantially L-shaped bimetallic brackets accurately secured to the frame of a color television picture tube undergo corrective flexures in response to temperature variations. These flexures compensate for the thermal expansion of the shadow mask by maintaining the mask in proper alignment between the glass panel and the electron source over the operating temperature range of the picture tube.
