Q: Tension cord not tight on Starling Tab-Tension, Saker Tab-Tension and Spectrum Tab-Tension ?

The Tension cords on the side of the screen do perform its pull effect to reduce side curving/curling, but Starling Tab-Tension, Saker Tab-Tension and Spectrum Tab-Tension use a weaved fabric. Unlike a flexible PVC fabric that allows for stretching and pulls to create a flat and taut projection surface, such as the one used on our CineTension B Series.
