Light Blockers For Blackout Shades

• Light Blockers are L-shaped pieces made from durable polystyrene, specifically designed to block light leakage by covering the gaps that blackout shades can’t reach. They can be installed in front of or behind your window coverings for effective light blocking. Since blackout shades are typically made slightly smaller than the window opening to prevent friction with the frame during operation, these gaps can allow light to seep through. Light Blockers address this issue, ensuring a darker, more comfortable space.
• Light Blockers are designed to block light along the sides of blackout shades, eliminating light slivers from gaps between the fabric and the wall, making your room up to 97% darker for an enhanced sleep experience. (Note: Shades not included.)
• These light-blocking strips can be attached either with screws for a secure fit, or with adhesive backing (3M tape). However, if removed, the adhesive backing will lose its stickiness and cannot be reattached. (Note: Not for use on stucco wall surfaces.)
• Our light blockers are easy to install in minutes with just a pencil, utility scissors, or tin snips, allowing for quick and effortless customization.
• Compatible with your existing blackout window blinds – works with 100% blackout roller shades and Dual Shade Harmony Duo Plus shades.

Note: The light blockers are designed specifically for the inside mount. Choosing this option includes a pair of light blockers, which will be cut into several pieces if the height is too long.
