Key Features

• Blackout Light Blockers for Side Light Gaps: Most blackout shades are made slightly narrower than the window frame to allow smooth operation, which can leave small gaps that cause unwanted light leakage. blackout light blockers help seal these side gaps and improve room darkening for better sleep, privacy, and comfort.
• Light Blocking Strips to Create a Darker Room: Designed as L-shaped blackout side tracks for window shades and blinds, these light blocking strips reduce light leaks around the edges of blackout blinds and shades. Perfect for bedrooms, nurseries, home theaters, gaming rooms, and light-sensitive sleepers.
• Dual-Sided Design for Better Blackout Performance & Style: The black inner layer helps block incoming light, while the white exterior blends with most window frames and home décor. Upgrade your existing blackout shades without replacing your current window treatments.
• Compatible with Roller Shades, Cellular Shades & More: Works with many inside-mounted window treatments, including roller shades, cellular shades, honeycomb blinds, zebra blinds, Roman shades, and other window shades. A simple blackout upgrade solution for any room that needs improved light control.
• Easy Peel & Stick Installation, Trim to Fit: Install your window light blockers in minutes with the included adhesive backing. Simply measure, cut the 58-inch light blocking strips to your desired size, peel, and stick along the sides of your window frame for a customized fit.
