Basic hand operated shutter with open-close positioning
The basic hand operated roller shutter can either be rolled fully up or down. When not in use, the roller shutter is hidden under its casing. To operate the roller shutter, simply open the window and rotate it 180 degrees until the sash automatically engages with the panzer. When closing the window, the shutter will now roll out automatically. To roll the shutter up again, rotate the window 180 degrees. A click-sound indicates that the shutter is detached from the sash.
