The use of TwinLine makes it possible to move a blind up and down freely and hold it in place wherever you wish in the window. The angle of the slats can be adjusted precisely using the rotary wheel built into the handle, thus making it possible to adapt light conditions even further to individual requirements. This handle is also available in aluminium and its purist appearance particularly suits the character of a horizontal blind. TwinLine makes all light and privacy settings possible according to mood or time of day.
