• Important: Accurate measurement is essential to get the right size for your class window. Before ordering, please read the instructions on how to measure and consult our "How to" image (in English).
• Standard & Custom Size: Important: Please add 3" to your window width and 3" to its length before choosing your size to ensure a proper fit. Available in 9 standard sizes that cover most interior windows in elementary, middle and high schools, as well as universities. We also offer custom sized blinds to fit all windows, such as side door, media center and entrance windows.
• Quick release velcro: Every second counts during a lockdown. The most effective roller blind must be able to be lowered and raised easily and safely.
• Easy to install, easy to use: Unlike many window blinds and blackout curtains, no tools, hardware, mounting brackets or drilling are required. Strong adhesive tabs hold the shade in place. Simply release the Velcro strap at the top to let the blind descend over the window and press the bottom of the blind in place to completely block out external views.
• Buy it now for more security: When an active shooter can see into your classroom, students and teachers become targets. A blackout blind can save lives, but it is crucial that it completely blackens the classroom to effectively ensure everyone's safety. Our blinds are a much safer choice than blackout paper blinds or blackout venetian blinds.
