Celexon Screen Roll Professional Plus 200 x 150 cm. Type: Roll screen. Dimensions: 208 cm x 158.5 cm. Projection type: Front projection. Weight: 9 kg. The soft-return mechanism makes it easier to retract the screen. The black masking and black backing ensure optimal image framing and increased contrast. The three-layer projection fabric with a gain factor of 1.2 provides excellent projection results under most ambient conditions. To operate the screen, pull it down about 5 cm and simply let go; it will retract on its own. Celexon has implemented this mechanism based on gears, which offers a significantly longer lifespan and consistent retraction force compared to conventional oil-based systems. The black backing prevents light from entering or escaping, allowing the screen to be used easily in front of a window. The screen can be locked at intervals of about 10 cm, enabling not only the 1:1 format but also other formats such as 4:3, 16:9, 16:10, or 21:9.
