• Specifications: Blackout strips are available in various lengths (12~59in) and can be cut to fit your window size. The width is fixed at 3.5cm/1.37in, and the thickness is 1mm (2mm with adhesive backing). They are made of PVC.
• Why you need blackout strips: Most blinds and roller blinds are narrower than windows. If your blinds or roller blinds consistently let in light, we recommend installing blackout strips.
• How they work: All blinds must be slightly smaller than the window opening to prevent light from getting in by rubbing against the window frame when raising or lowering the blackout curtain. A blackout strip is an L-shaped plastic strip that can be installed on the front or back of the blind to block the unblocked portion of the window.
• Purpose: Suitable for the sides of blackout curtains (excluding the blackout curtain itself)—blackout strips prevent gaps between the blind and blackout curtain. Effectively blocks light from entering the room from the sides of the blackout curtain.
• Easy to use: Simply peel off the adhesive backing and stick it to the side of the window. For best results, the blackout strip should be placed as close as possible to the blackout curtain.
