<p>The box (1) has a longitudinal opening (7) for passage of a roller shutter. Side guide elements form tulips (10), where each tulip is at top of a slide to guide an entry of apron of the shutter in the slide. Each tulip has a vertical through-passage (14) opened laterally and delimited by guide walls (11, 12) connected by a bottom wall (13). Each of the tulips is attached by a fixing unit formed of longitudinal groove and rib, with a rear free longitudinal edge (41) of a lower horizontal wall (4) of the box and/or with a lower edge (21) relative to a rear vertical wall (2) of the box.</p> |
