• 【Why we need to install light blockers for shades】Most blinds and blackout shades are made slightly narrower than the window frame to allow smooth raising and lowering. This design often causes light leakage from the sides. If your blackout blinds or shades still let in unwanted side light, this common side gap issue can reduce room darkening. ZSTARR light blocking strips are designed to help solve this problem and improve overall room darkening performance.
• 【Reduce light leakage】ZSTARR L-shaped PVC blackout light blockers are installed along the sides of window blinds and shades to reduce light leakage caused by side gaps. By blocking light from the edges of blackout blinds and shades, they help create a darker environment that supports better privacy and quality sleep. Designed to reduce side light gaps, not to replace blackout shades.
• 【Easy To Install】No tools required. Simple peel-and-stick adhesive installation. Simply peel off the adhesive backing and stick the light blockers to the side of your inside window frame. Stop the light from coming in through the sides. The light blockers can be combined or trimmed with standard household scissors for a custom fit. Size: 79 x 1.6 x 0.9 inches (4 PCS). For maximum coverage, install as close to the blackout shades as possible. Please refer to our installation video for proper installation and alignment.
• 【Light-blocking Side Tracks】These blackout side tracks are ideal for night-shift workers, light-sensitive sleepers, or anyone creating a darker room during the day for sleep, movies, or gaming. Works with cellular shades, honeycomb blinds, roller shades, roman shades, and more. Recommended for inside-mount blinds with flat window frames and at least 1 inch window depth for best performance. If the light blockers are not suitable for your windows, they can be returned within 30 days for a refund.
