<p>The window roller blind has a lower rail (4) which is hollow and hang from the blind cord end sections (62,63,64,65) which are weighted at their lower ends. The lower rail has two spaced inlet openings (41) for the cords and two further spaced outlet openings on its lower face. The cords cross over inside the rail to provide a friction engagement with the rail, so that it can be fixed at a set height.</p> |
