Dark 10, which can be configured as a free-hanging blind, is a cassette system that can black out the room completely when fitted with side channels (in a recess or flush with a wall). Hardware is made from extruded aluminium in a white heatcoated finish or ral finish.

With ita quality mechanical parts, dark 10 can be easily used to cover large openings, up to 4,2 meters across, even in the simple chain-operated manual version (comes as standard with gear reduction clutch).
