IMPORTANT: Measuring accurately is essential to get the right size for your classroom window. Before ordering, please read the instructions on how to measure and see our "How to Do" picture. Standard and custom size: important: please add 3 inches to the width of your glass and 3 inches to your length before choosing your size to ensure a good fit. Available in 9 standard sizes that cover most interior windows in primary, middle and secondary schools, as well as universities and colleges. We also offer custom sized blinds to fit all windows, such as side lights, media centers and entryways. Quick Release Velcro Strap: Every second counts during a lockdown. The most effective shade should be easily and quickly attached to the top and bottom of the window. 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 so that the sun shade falls on the window and press the bottom of the shade 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 darkens the classroom to effectively ensure everyone's safety. Our blinds are much safer options than blackout paper blinds or blackout blinds for windows.
