The grid (14) is fastened to cross webs (11) fitted into opposite cut-outs (5,6,7,8) in the top of the long sides (2,3) of the channel body (1). The ends of the webs pass through the cut-outs. The long channel sides are secured against sideward bending by stops on the cross webs, which engage on the outer faces of the sides. The grid is connected to the cross webs via screws (13) passing through the webs and engaging with a nut below.
