The semi-circular shapes of the shutter will give the window an elegant appearance. There are also available semi-circular caps for the guide rails. The size of the box depends on the whole height of the shutter and the type of armouring. There are versions with or without mosquito nets.
The whole shutter is installed on the building facade.
The drive (belt or cord) are conducted through the rear of the box, then through an opening in the wall into the rooms.
We perform this installation after the installation of windows.
The whole shutter is screwed on a window frame.
The output of the drive (cord) is through the window frame.
One should remember that one should insert the box of the shutter with the placed guide rails into the window recess.
