• Winsmar light blocking strips are available in L-shaped custom lengths 2pcs, ranging from 59 inches to 115 inches. They are made of light-absorbing PVC plastic material.
• 【Why we need to install light blockers for shades】Most blinds and shades are smaller in width than the window to avoid the fabric rubbing against the wall when the blackout shade is raised or lowered. If your blinds or shades are always leaking some annoying light, then we suggest you install WINSMAR light blocking strips.
• 【HOW THE LIGHT BLOCKER WORKS?】All window treatment must be made slightly smaller than the window opening to prevent rubbing on window frame when blackout shade is raised or lowered, so light may shine through. Light Blockers are an L-shaped piece of plastic that goes in front of or behind your window covering to block the part of the window that is not covered.
• 【BLOCKS 100% of LIGHT】 Along sides of Blackout Window Blinds (Does not include shade)-WINSMAR Light blocker prevent light gaps on blinds and windows. Stop the light from coming in through the sides of your Blackout Blinds & shades, ideal for office, media rooms, bedrooms, and wherever naps are taken.
• 【Easy to Use】Just peel off the sticky backing and stick it onto the side of your window. The light blocking strips should be placed as close to the blackout window shades as possible to achieve the maximum light blocking effect. It works on cellular shades, honeycomb blinds, roller shades, blinds, roman shades and many other types of window coverings.
