Abstract
A louver construction comprising a grid formed of cubes molded unitarily with a flange extending around the periphery of the grid. The cubes include a border row making up the periphery of the grid. The cubes in the border row have different dimensions than those inside them in the grid. The flange may vary in width but the outside dimensions of the louver remain the same. As a result, the same size louver grids will fit different size light box openings.
