The SINOSCREEN SL178 is a professional manual pull-down projection screen designed for reliable everyday use in education, corporate presentation spaces, and residential installations.
This model features a slow retraction control mechanism, allowing the screen to roll up smoothly and steadily—helping prevent sudden snap-back and supporting long-term durability. With a nominal size of 178 × 178 cm in a 1:1 square format, the SL178 is well suited for presentations, training content, and general projection applications.
The screen surface is engineered to deliver clear and consistent image reproduction with comfortable visibility for group viewing. The robust metal housing supports wall or ceiling installation, enabling a clean and practical integration into a wide range of spaces.
