Dual Roller shades are currently only available with a bracket headrail and not a cassette headrail, as shown here.

Dual Roller Shades are two shades together, with one positioned in front of the other. Choose any two Designer Roller or Designer Screen fabrics, one for the front shade and one for the back shade. 

With the Alustra ^® Woven Textures^® roller shade style, the rear shade is offered in a light-filtering or room-darkening liner. Choosing fabrics of varying opacity allows for maximum light control and privacy. Each shade operates with its own continuous beaded cord loop for even more versatility.
