Package: This contains 2 L-shaped Light Blockers, made of light absorbing PVC plastic material, which can be cut. The size is 57" x 1.38" x 1.38". Compared with similar products, the width is wider and firmer, and the shading effect is better.
Action Principle: In order to avoid the friction between the edge of the blind and the window frame, the width of the blind is usually smaller than the window frame, which will lead to light gaps on both sides of the blind. The widened L-shaped baffle of the Light Blockers perfectly solve this problem.
Simple Installation: First measure the height of the window frame, then cut the Light Blockers to a suitable length along the cross section with scissors, remove the red double-sided adhesive film on the back. Finally, stick the Light Blockers on the inner frame of the window to make the edge of the roller shades fit it.
Better Effect: The Light Blockers are used to stick on the window frames on both sides of the blind, covering the light gaps, adopting the manufacturing process of side widening, achieving 100% blackout. It is an ideal choice for offices, media rooms, bedrooms and rest places. It is very suitable for shangri-la shades, cellular shades, day & night shades, zebra blinds and roller shades.
