Celexon Screen Roll Professional Plus 240 x 240 cm. Type: Roll screen. 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 implemented this mechanism with a gearbox, which offers a significantly longer lifespan and consistent retraction force compared to traditional 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 exiting, allowing the screen to be used easily in front of a window. The screen can be locked 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.
