Abstract
A tensioned shadow mask/frame assembly includes horizontal top and bottom members and vertical side members. One of the horizontal members is permanently affixed to the side members and the other horizontal member is slideably supported on the side members. The horizontal members are biased apart to put tension on a shadow mask which is stretched across and permanently affixed thereto. The cross sectional configuration of the horizontal members is an acute angle having a long side and a short side joined at a rounded apex to maximize the stiffness of the members.
