Classic roller styling is marked by clean, simple lines + exceptionally smooth, dependable operation. Shades are raised, lowered and positioned with an effortless push up or pull down on the control handle, eliminating traditional pull cords which can be dangerous to small children and pets. Specially-woven fabrics let you see out clearly while reducing glare and filtering out up to 97% of UV rays. Select from three openness levels (3%, 5% and 10%) for the amount of light blocking you need. For > MORE nighttime privacy, we recommend layering Drapery over Solar Roller Shades. NOTE: minimum width with Alloy, Linear, Link and Optix fabrics is 25"; 19 1/2" for all other fabrics. Maximum width is 92"; maximum height is 96".
