The rectractable reflecta projection screen is installed in a profiled sheetmetal case and is operated with the locking mechanism with the soft lift function. When pulled slightly downwards, the projection screen automatically retracts slowly and safely to the tube. A soft brake avoids a fast and uncontrolled retracting. The screen can be stopped at any intermediate height to adjust to the various projection formats. With the lightproof rear coating, it can be used even in front of a window. The black border makes the screen particularly suited for home theatres.
