Toperblinds Light Blocking Strips for Window Blinds — White 15.75" Connectable PVC Side Tracks, Self-Adhesive 10-Pack for Better R

Toperblinds Light Blocking Strips are self-adhesive PVC side tracks that attach to indoor blinds and shades to reduce edge light and improve room darkening.

These connectable, white blackout side tracks come as a set of ten 15.75" strips with upgraded adhesive and included blackout tape, designed to minimize the narrow gaps where light leaks through standard blinds. They are intended for interior use on smooth window frames or walls and are compatible with many horizontal and vertical blind systems to create a darker, more private space without replacing your existing window coverings.

How do these strips reduce light around my blinds?

The PVC strips create a tighter seal between the blind or shade and the window frame, sealing the slim gaps that let light in at the sides. Because they run along the blind edges they complement existing slats or rollers rather than altering the blind mechanism.

• Connectable 15.75" sections that bridge seams for taller windows
• Included blackout tape to seal small gaps at seams or joins
• White finish blends with many window trims while blocking edge light

How easy is installation and removal?

Installation is a simple peel-and-stick process using upgraded 3M adhesive; press each strip onto a clean, smooth surface and trim if needed. The adhesive is designed for repositioning if you need to correct placement, but it needs a smooth substrate to adhere reliably.

• Peel backing and press along the blind edge or frame
• Repositionable 3M tape helps correct alignment during fitting
• Not recommended for rough, textured, or freshly plastered walls

Will these fit my windows and which rooms benefit most?

Each strip is 15.75" long and the set includes ten pieces, so they suit a range of window heights up to about 78" when connected vertically. They work best on standard indoor blinds and shades where side light is the main issue.

• Fits many horizontal and vertical blind profiles without hardware changes
• Use multiple strips end-to-end for taller windows up to roughly 78" high
• Most effective on smooth frames in bedrooms, media rooms, and offices

What should I expect about performance and limitations?

The strips significantly reduce interstitial light but may not produce full blackout in every installation because blind type, fit, and wall texture affect results. They’re a low-cost option to improve darkness and privacy without replacing blinds, though a small amount of light leakage can remain in some setups.

• Substantial improvement in edge light control, not guaranteed full blackout
• Effectiveness depends on blind type, installation quality, and wall smoothness
• Customer support available for size or fit questions before purchase

Who is this product for? Toperblinds Light Blocking Strips suit renters and homeowners who want to reduce side light and boost privacy without installing new blackout blinds. They’re also useful for people creating darker spaces for sleep, media viewing, or shift-work rest, provided the window frame is smooth enough for adhesive mounting. If you have textured walls or need a permanent blackout solution, consider measuring and checking compatibility with our customer service first.
