WEFFORT LIGHT BLOCKERS, REDUCE LIGHT GAPS, ENHANCE PRIVACY AND LIGHT CONTROL

Help minimize unwanted light around your blackout shades with Weffort Light Blockers. Designed to cover side gaps where light may slip through, these slim strips provide a simple, practical way to improve room darkening without adding bulky side channels. They are a useful finishing touch for a more comfortable, private indoor space.

FEATURES AND BENEFITS

L-Shaped Design for Light Blocking: Made from durable polystyrene, Weffort Light Blockers feature an L-shaped design that helps cover the side gaps around blackout shades. They can be positioned in front of or behind your window coverings to reduce unwanted light seepage along the edges.

Reduce Side Light Gaps: Blackout shades are typically sized to allow smooth operation without rubbing against the window frame, which can leave narrow gaps along the sides. Light Blockers help cover these openings, improving room darkening and creating a more comfortable environment for sleeping or relaxing.

Flexible Installation Options: Choose adhesive-backed nano tape for a installation or use screws for a more secure fit. Light Blockers can be installed to suit your window setup and mounting preferences. Please note that the adhesive backing cannot be reused once removed, and installation on stucco surfaces is not recommended.

Customizable Length for a Better Fit: Our light blockers can be trimmed to fit your window height for a more tailored installation. Cutting with suitable utility scissors or tin snips to accommodate your window dimensions if too long.

Simple DIY Installation: Install your Light Blockers with basic tools and without replacing your existing shades. With a few simple measuring and cutting steps, you can add side light-gap coverage to your window setup.
