Cordless Roller Blackout Window Shades for Home/Office: 20''W x 72''H, Grey

About this item

• Cordless window blinds feature a durable constant force spring-loaded mechanism that has been tested for 5,000 lifts and pulls per blind. This design allows for easy and even raising and lowering, while maintaining balance automatically. The absence of cords makes them safe for children and pets.
• Adjust the rebound position and speed: ⭐Adjusting the rebound speed: open the right side cover and adjust the screw clockwise to make the rebound speed slower and counterclockwise to make it faster. ⭐Adjusting the rebound position: open the left hood and adjust the screw counterclockwise to stop the roller blinds in the desired position and return to this position when contracting the roller shades.
• A standard 1/5 inch deduction is made to the top rail width for a proper INSIDE MOUNT fit. The true blinds size is 19 4/5" W x 72" H. ⭐Please be informed that the fabric width is 1 inch narrower than the top rails(NOT the window). ⭐There is a 1/2 inch light gap on both side. Please read the picture to learn the light gap may happen on the window.
• ⭐For inside mount, window frame should have at least 2” depth. ⭐For outside mount, we recommend Shades Width=your window outer frame width + (2-4)inch, shades length should be at least 2” longer than the window length for better coverage.
