✅ Key Features
100% Side Light Blocking
Most blinds are narrower than window frames, allowing light to leak in from the sides. These strips block those gaps for true blackout.
Durable L-Shaped Aluminum Design
Made from UV-blocking aluminum, the strips reflect light, reduce heat, and last longer than plastic alternatives.
Universal Blind Compatibility
Fits roller shades, zebra blinds, honeycomb shades, roman Blinds, and cellular blinds.
Custom Sizing
Hand-cut to your measurements or easily trimmed at home using a basic saw.
Color Options
Available in 7 different finishes to match your interior décor.
Set Configuration
Sold in pairs (2 strips per set) for both sides of the window.
Installation Guide: Two Easy Options
You can choose either a drill-mount or no-drill adhesive installation method, depending on your surface and needs.
Option 1: Drill-Mounted Installation
Measure & Cut
Use an electric saw to cut the strips to match your window height. For chain-operated blinds, trim a small notch as needed for bead clearance.
Drill Holes
Without foot brackets: Drill two holes at the top and bottom quarter-points of each side.
With foot brackets: Drill at the top and middle quarter-points.
Insert Wall Plugs
Push expansion plugs into the drilled holes.
Align & Mount
Align the L-shaped strip against the side of the window frame, and secure it with screws. If using foot brackets, install them at the bottom before tightening.
Tighten All Screws
Ensure a firm and flush fit.
Option 2: No-Drill Adhesive Installation
Surface Prep
Clean the surface thoroughly to remove dust or grease.
Peel & Stick
Apply strong double-sided mounting tape (not included) along the flat back of the L-shaped strip.
Press Firmly
Stick the strip onto the window frame and press evenly for at least 30 seconds.
⚠️ Note: Adhesive installation is recommended only on smooth, flat surfaces. Avoid using it on uneven or dusty areas.
