Da-Lite Model C Series Projection Screen - Wall or Ceiling Mounted Manual Screen for Large Rooms (70" x 70")

The Da-Lite Model C Series Projection Screen is built for serious presentations in large rooms, training facilities, and collaborative spaces where image quality and dependable operation matter every day. This manual, pull-down screen is designed to be mounted either on the wall or from the ceiling, providing flexible installation options that adapt to room geometry, seating arrangements, and projector positioning. The 70" x 70" viewing area delivers a generous, square format that makes it easy to read fine print, view detailed graphics, and share content with large groups without compromising clarity. The Model C is engineered to stand up to high-traffic environments—classrooms, conference rooms, and corporate training spaces—where reliability, ease of use, and long-term durability are non-negotiable. With a focus on maximized projecting efficiency, the screen surface and precision mechanics work together to deliver bright, crisp images with accurate color reproduction, even in rooms with ambient light.

• Versatile mounting options: The Model C is designed for both wall-mounted and ceiling-mounted installation, giving you the freedom to choose the configuration that best aligns with your projector, seating plan, and room architecture. This flexibility helps maintain optimal sightlines, reduces glare, and ensures that the projected image remains unobstructed for every audience member. Whether your ceiling height is standard or high, the Model C can be positioned to achieve the most comfortable viewing angle across the room.
• Premium manual operation: The screen uses permanently lubricated steel ball bearings paired with nylon bushings and a heavy-duty spring assembly, delivering exceptionally smooth, quiet, and dependable operation. The manual mechanism requires no power source, which simplifies installation and reduces maintenance concerns. With consistent pull-down tension and controlled retraction, the screen resists sag over time and maintains a flat, stable surface for a pristine image from near or far seats alike.
• Large, square-format screen for collaboration: At 70" by 70", the square-format viewing area is ideal for group work, dual-projection setups, and environments where participants sit in various orientations. The generous size supports detailed diagrams, spreadsheets, and multimedia content, while the square aspect minimizes distortion when presenters rotate content or switch between portrait and landscape layouts during a session.
• Durable construction for daily use: Built to endure frequent deployments, the Model C combines a robust housing with a tensioned projection surface designed to resist wear and warp. The steel casing shields the internal mechanism from impact and dust, while the surface material is selected for durability, easy maintenance, and long-term image stability. In busy classrooms and corporate training rooms, the Model C maintains consistent image geometry and reliable operation, even after thousands of pull-downs.
• Maximum projecting efficiency and image clarity: Da-Lite’s engineering focuses on optimizing light control and optical performance. The combination of a high-quality projection surface and precise rolling mechanism yields bright, uniform images with strong contrast and wide viewing angles. The screen is designed to work well with a broad range of projectors, offering crisp text, vibrant graphics, and accurate color reproduction across seating rows—so every participant experiences the intended visuals with minimal eye strain.

how to install Da-Lite Model C Series Projection Screen

Proper installation maximizes performance and extends the life of your Model C screen. Begin by selecting the mounting location that provides optimal viewing angles and aligns with the projector’s throw distance. Confirm that your wall or ceiling structure can support the screen’s weight and that you have access to sturdy mounting points, such as studs or joists, or appropriate anchors for the chosen surface. Use the included hardware and follow the manufacturer’s guidelines for bracket placement and alignment to ensure the housing sits level and square relative to the screen surface. After attaching the mounting bracket, secure the screen housing to the bracket and verify that the pull-down chain or operating mechanism moves smoothly without binding. Check the tension and adjust as needed to ensure the screen stops in a fully extended, flat position and retracts evenly without sagging. Finally, test the screen with your projector to confirm image alignment, keystone correction, and focus across the entire surface. Keep the screen clean by wiping with a soft, dry cloth and store in a dry, clean environment when not in use to protect the projection surface and mechanism from dust and moisture.
