The Draper 241059 Ultimate Folding Screen is the first screen manufactured with 100% CNC (Computer Numerical Controlled) components and assembly. The tubing is CNC machined; surfaces and borders are CNC cut; even rivet and snap holes are CNC placed.The portable Ultimate Folding Screen's design simplicity and rugged components withstand the rigors of repeated set-ups and tear-downs in demanding applications. This projection screen features a lock-and-load latch that bites down when the viewing surface is attached providing an extremely rigid frame. The resilient latch retention spring is captured and constantly flexed to prevent the screen from dislodging. A flat viewing surface offers a better image quality that accommodates today's varied viewing formats. Anodized aluminum tubing provides stability for larger projection screen sizes that are ideal for churches and expo halls.
