<p>The assembly has parallel bars fixed to a support (9) that has a set of coupling units coupled to another set of coupling units of the bars to secure the support to the bars. The latter units constituted by relief and/or hollow shapes are arranged on the bars by retracting its visible front faces. The shapes of the units have dimensions relative to dimensions of the grid, where the dimensions are less exposed, when observing the totality of the grid in absence of the support. The two sets of coupling units are respectively constituted by snap ribs (27, 29, 31) and ribs (35, 37-39).</p> |
