WINSMAR 100% Blackout U-Channel Aluminum Strip

These 58″ long L-shaped PVC strips are designed to block light from the sides of curtains and blinds. They help reduce light leakage in bedrooms, home theaters, and nurseries, and work with various blind styles including cellular shades and honeycomb blinds. The strips are trim-to-fit and can be cut with household tools to match window dimensions. They provide a practical, budget-friendly option for achieving deeper room darkening without replacing existing shades.
ZSTARR PVC Light Blockers Side Tracks for Window Shades

These ZSTARR light blockers use an L-shaped PVC profile to curb side light leakage. The design aims to fit closely along the edges of window shades, enhancing room darkening without replacing the shade itself. Installation includes simple alignment and the option to trim for a custom fit. The product emphasizes reducing side gaps to improve privacy and sleep quality, making it a solid option for bedrooms and nurseries alike.

The kit includes 3M adhesive and screws, providing flexible installation options: quick peel-and-stick or a more permanent screw-on method. The design minimizes light leakage from the frame edges to create a darker room environment, beneficial for sleep and privacy in bedrooms and nurseries. A trimming capability allows customization to fit various window widths.
Buying Guide
- Material and durability: Aluminum tracks offer strength and longevity, while PVC options are lighter and typically easier to install. Consider the window environment and potential moisture exposure when selecting material.
- Installation method: Decide between screw-on permanent fixtures versus adhesive-backed, removable tracks. Reusability and wall integrity after removal are important for renters or future redecorations.
- Width and coverage: Match the track length (commonly around 58″ to 58.5″) to your window width. Verify the ability to trim or cut to achieve full side coverage without gaps.
- Compatibility with shade types: Check whether the track supports cellular, honeycomb, roller, or blackout shades. Some products specify inside or outside mount suitability.
- Light-blocking effectiveness: Look for L-shaped or U-channel designs that press against the shade edge to reduce side leakage. U-shaped or aluminum options typically provide a stronger seal.
- Ease of use and maintenance: Reusable components, simple alignment, and clear installation instructions improve long-term satisfaction. Consider cleanability and how the strips react to daily use.
- Aesthetics: White or neutral tones blend with most window frames. Some products offer color options to better match or contrast with existing decor.
- Safety considerations: For homes with children or pets, cordless or cordless-friendly designs are preferable to minimize hazards near windows and tracks.
When evaluating options, weigh the trade-offs between stronger light-blocking performance and ease of installation. For rooms requiring maximum darkness—such as bedrooms or nurseries—aluminum or thick PVC tracks that closely hug the shade edges tend to deliver better results. For renters or temporary setups, adhesive-backed and reusable screw-on solutions may be more practical, even if slightly less durable over time. Always verify the installation method matches your window structure and shade type to ensure optimal performance.
