The cassette headbox, (55mm / 2 1/4 square), painted white fixes onto the window sill or can be fixed to the wall outside the recess. Brushes in the headbox prevent dust entering. The cords operating the blind tie off to a cleat. Universal wall or ceiling diverters are supplied - there's no great skill involved in fitting these blinds. Unlike with the 50:50 blinds the window can be obscured all the way to the top - alternatively, in any position in between. |
