The ScreenLine® SL20P system comprises a venetian blind incorporating a 12.5 mm slat designed to be integrated in a double-glazing unit with a 20 mm. cavity. The manual tilt only function is operated via a wire drive by an external knob.

The specially designed corner key containing the rotational magnet is connected to the external knob by a flexible drive cable located within the glazing cavity of the window frame. Due to the narrow cavity (20 mm), the system can be used in almost all types of existing window frames, whilst the special design allows the aesthetic quality to be maintained in whatever environment it is installed. The only visible control is the external knob fixed to the window frame, allowing the glass surface to remain completely free and easy to clean.

These particular features make the SL20P system ideal for public environments such as hospitals or government offices where a variety of people need to operate this simple but highly protected system. The ScreenLine® SL20P may be modified to incorporate a 16 mm slat for integration in a 24 mm cavity unit.
