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 shade band across the opening it creates resistance as it tightens the opposing spring, in the fabric tube, providing shade band taughtness. The size and weight of the shade will determine if idler rollers, guide cables and/or guide track are necessary.
