The most effective blind should be able to be easily and quickly attached to the top and bottom of the window. Easy to install, easy to use: unlike many blackout blinds and curtains, no tools, hardware, mounting bracket or drilling are required. Strong adhesive tabs hold the blind in place. Simply detach the Velcro strap at the top so the blind falls on the window and press the bottom of the blind in place to completely block the view of the intruder. Don't wait until it's too late: when an active shooter can see into your classroom, students and teachers become targets. A blackout curtain can save lives, but it is crucial that it completely obscures the classroom to effectively guarantee the safety of everyone. Our blinds are much safer options than paper blackout blinds or blackout blinds for windows.
