The Mainstays Cordless Room Darkening Vinyl Blind features improved light control over standard vinyl blinds. The upgraded room darkening slats dim the room from outside light making these blinds ideal for rooms that require darkness and privacy but not in need of total blackout. The new cord-free design provides a clean tangle-free look to the window and creates a safer environment for children and pets. To operate the blind simply lift or lower the bottom rail and adjust it to your desired height. To maintain the blinds wipe clean with a soft cloth to keep it looking new. The installation kit includes all mounting hardware and easy-to-follow instructions that make installation a breeze. Please note that a 0.5-inch deduction will be taken from the width of the blind to allow proper installation inside the window frame.
