Abstract: A circuit card frame comprising one-piece molded panels and sidewalls. The panels have U-shaped tenons adapted to be inserted in openings in the sidewalls and slid into place along locating tongues and ridges disposed in the openings. The panels have elastic tongues adapted to be deflected along ramps disposed between pairs of tenons at the ends of the panels when the panels are slid into place, the free edge of the elastic tongues abutting an end of the ramps to lock the panels on the sidewalls. A mounting clip may be provided for holding a mothercard to a panel.
