Our full-coverage roller shades help block the sun glare and heat, but not the view. They are designed to fit most vehicles. Our roller shades feature suction cups to help keep the shades secure and clips that slip over the top edge of the window. Our roller shades roll down for full coverage and easily roll up with our quick- retract button. How to Use the Suction Cup Correctly: 1.) Attach the suction cup to the roller shade. 2.) Clean the window thoroughly using a damp cloth or towel. 3.) Firmly press the suction cup against the window, ensuring no air remains trapped inside.
