ABSTRACT:
There is disclosed a refrigerated display cabinet having a refrigerating chamber and a mechanical chamber, and an access opening into the refrigerating chamber that is adapted to be opened and closed by a transparent cover panel sliding longitudinally of the access opening. The cover panel is mounted on guide rail mechanisms each of which comprise a frame with wheels and rail elements. Each frame is provided with two sealing flanges which extend vertically and horizontally from one edge of the frame into sealing engagement with the rail element when the transparent cover panel is closed thereby closing or sealing the gap between the frame and the rail elements to prevent leakage of cooled air from the refrigerating chamber.
