Celexon Roller screen Professional Plus 300x225 cm 4:3

Celexon Professional Plus Projection Screen 300 x 225 cm. Type: Roll-up screen. Dimensions: 312 cm x 239 cm. Projection type: Front projection. Weight: 18 kg. The soft-return mechanism allows for easy retraction of the screen. The screen features black masking and a black backing. The three-layer projection fabric with a gain factor of 1.2, a stabilizing fabric layer in the middle, a black rear coating, and a matte white front coating delivers excellent projection results under most ambient conditions. To operate the screen, pull it down about 5 cm and simply let go. The screen will retract automatically. Celexon has implemented this mechanism based on a gearbox, providing 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 backing prevents light from entering or exiting, allowing the screen to be used easily in front of a window. The screen can be locked at intervals of approximately 10 cm, enabling not only the 1:1 format but also other formats such as 4:3, 16:9, 16:10, or 21:9.
