Light Blockers Blackout Side Tracks, PVC Blackout Side Strips for Window Shades and Blinds, Light Blocking Strips for Bedroom 2 Pcs(White, 58")

Needs to be assembled as close to the blinds as possible. Works great for me.

Exactly as described

These are good with very strong adhesion, my only issue is they are very shiny- so if the sun hits them through even a very thin gap the reflect like a mirror into the room until the sun moves.

Great product and amazing customer service. Ours came broken and they worked with us to send a new one right away!

We have blackout blinds but the edges are open. Was hoping this would keep the light out but it is not blackout so light comes through.Install was easy since it was just sticky tape on the back. Be careful because it is strong so once it’s on it will take your wall off if you try to take it off. Decent but could be better

I ordered these to block the light coming in around the left and right sides of our bedroom blinds. I had to do some custom trimming to allow for the blind cords to come through up in the top corner on the left side. I used a power drill file and made a small 1/4” U-shaped channel for them to come through which you can see in the 2nd photo. These devices are sturdier than I had anticipated so cutting them required a bit of effort using tough tin snips.I still have light intrusion along the bottom so I may go ahead and order another set. The picture shows one on the LEFT and one across the BOTTOM. I still need to add one to the right side but I thought you might like to see how it looks without it, so you can see the difference.FYI: This picture was taken during the middle of the day when it was bright sunshine just outside the window.Fair warning: if your window is not exactly plumb and square, you may have problems with gaps in the adhesion.Overall, I think they are going to help about 90%.

Our RV shades are great but light from outside lights as well as the ability to see in at night was fixed by this. I couldn’t be happier with how good the work and look!

Arrived in perfect condition and the custom measurements are perfect. The halo light issue from the roller shades has finally been fixed, and I’ve already ordered again for my other windows.
