The slats are 50 x 0.23 aluminium slats The blinds are raised and lowered with cords and tilted with a clear wand. Cords are colour matched to the slats. The standard brackets are spring loaded steel brackets - they can be fixed upwards or to the face of an opening. These are not visible from the front of the blind. There is a side mount box bracket option available. however, we only recommend using it with a Fascia as the colours are not an exact match to the headrail.
