When making the lamp body, the lower parts of the opposite box faces are pressed in the form of L-shaped profile, width and height of which are equal to width and height of braces, thus whenever they are fixed aflush with the lower rib, the upper faces of all L-shaped profiles form a single horizontal support surface of the transparent tile installation. |
