For shades deployed from the bottom of the window Mariak Industries Inc. offers Bottom Up shades. Fabric rolled on the tube is placed inside of the aluminum enclosure in the bottom of the window. Cables pulling the hem bar are secured to the upper tube which contains the lifting AC motor. The upper tube is mounted on the brackets and concealed in an upper aluminum enclosure at the top of the window. Lifting cables are typically attached at the ends of the hem bar to provide clear view or they follow the mullions of the window per costumer specification. Optional snap-on side channels are also available for this product. Typically 4 ½” by 4 ½” “L” fascia are used as an enclosure. For larger skylights, enclosures measuring 5 ½” by 5 3/8″ and 7″ by 9″ are also available.

The Bottom-Up Shade that Mariak Industries Inc. offers can be configured with motor on the top or with both fabric and the motor on the bottom. The fabric on the tube is placed closer to the window while the motor winding cables is placed away from the window. Both the fabric and the motor tube are suspended from one 5 ½” by 7 3/8″ bracket. Rectangular end caps cover both ends while the aluminum fascia covers the top. A pulley system guides the cable from the motor tube to the top of the window and down to the hem bar finishing the shade. Cables could be placed at the end of the shade or follow the mullions, per customer request.
