Keego PVC Light Blocking Strips for Window Shades & Blinds — 58.5" L-shaped Side Seal, Adhesive & Trim-to-Fit

Keego Light Blocking PVC Strips are L-shaped, cut-to-fit side panels that seal the gaps beside blackout blinds and shades to prevent side light leakage.

If your blackout shades or cellular blinds still let in bright slivers of daylight along the edges, these PVC light blockers create a simple, low-profile barrier. Each strip is made from rigid, light-absorbing PVC and includes adhesive backing so you can mount it inside the window frame or directly adjacent to the shade. They come in a standard length and can be trimmed at home to match your window height.

How do these Keego strips stop side light without altering my shades?

The strips act as narrow L-shaped panels that occupy the small space between the shade and the window opening, blocking the route where light sneaks in. They don’t replace your shade — instead they work alongside it, positioned as close as possible to the fabric or slats for the best seal. Installation is non-invasive and reversible when you remove the adhesive.

• Install in front of or behind the shade for flexible placement
• Cut to height with heavy scissors or a hacksaw for a custom fit
• Use the peel-off backing for quick, adhesive mounting

Will these strips fit my window size and shade type?

Keego strips come in a standard dimension (58.5" x 1.2" x 0.9") and are designed to be trimmed at home so they adapt to most window heights. They are compatible with a wide range of treatments, including roller shades, cellular (honeycomb) blinds, roman shades, and standard horizontal blinds. Measure the gap between your shade and frame and trim the strip to match.

• Standard length allows cutting for tall windows
• Works with diverse shade materials and mounting styles
• Rigid PVC resists warping and maintains edge coverage

How easy is the installation and removal process?

Installation is straightforward and requires no tools beyond scissors or a hacksaw for trimming. After cutting to size, peel the adhesive liner and press the strip against the frame or jamb; hold briefly to secure. Removal is clean and simple — peel away the strip and discard or reuse with fresh adhesive if desired.

• Minimal tools: sturdy kitchen scissors or a hacksaw for precise cuts
• Peel-and-stick backing for fast, tool-free mounting
• Non-permanent attachment for easy removal or repositioning

How much light reduction can I expect from Keego blockers?

These L-shaped PVC pieces are built to stop the small but bright slivers of daylight that appear at the sides of many blackout setups. While they do not change the opacity of the shade fabric itself, they dramatically reduce side infiltration when positioned close to the shade edge. For full room darkening, combine them with a properly sized blackout shade and careful placement.

• Blocks most side-gap light that standard shades miss
• Optimized for narrow gaps where direct sunlight enters
• Pair with blackout fabric for near-total darkening in the covered area

Who is this for? Homeowners, renters, photographers, shift workers, media-room owners, and anyone seeking improved darkness without replacing existing window treatments will find these Keego light blockers practical. They’re especially useful if you want a quick, low-cost solution to eliminate distracting edge light from blackout blinds and shades while keeping the original window coverings intact. Keego includes a 30-day return policy if the strips don’t meet your needs.
