Celexon Screen Roll Professional Plus 280 x 210 cm. Type: Roll screen. Dimensions: 292 cm x 224 cm. Projection type: Front projection. Weight: 10 kg. The soft-return mechanism makes raising the screen easier than ever before. The screen features black masking and a black back. Pull the screen down about 5 cm and simply let go. The screen will retract automatically. Celexon has integrated this mechanism based on gears, which offers a significantly longer lifespan and consistent retraction force compared to conventional oil-based systems. The black masking ensures optimal image framing and enhances the contrast of your projection. The black back prevents light from entering or escaping, allowing the screen to be used effortlessly in front of a window. The screen can be locked at approximately every 10 cm, enabling not only the 1:1 format but also other formats such as 4:3, 16:9, 16:10, or 21:9.
