A Tensioned SkyLighter Roller Shade is a motorized shade designed for applications that require a taught flat shade like that shown above. The system consists of two synchronized tubular motors and a special electronic control unit to control the taughtness of the shade band. One motor is for fabric roll-up, the second motor is for cable take-up. Skylighter can also be tensioned using a motor and a spring.
A Non-Tensioned SkyLighter Roller Shade is a single tubular motor and spring system for angled, gravity drop or horizontal shades up to 6 x 8 ft (183 x 245 cm). As the motor in the cable take up tube pulls the shadeband across the opening it creates resistance as it tightens the opposing spring, in the fabric tube, providing shadeband taughtness.
