Now you can breathe a sign of relief and fresh air at the same time. This innovative safety device effectively prevents curious toddlers from opening windows and falling out. Designed to work on double-hung or sliding windows, the wedge can be positioned along the length of a strip of Velcro, which is adhered to the window pane. You control the height and width of the window opening by moving the wedge to the designed position.

It's easy to install: Simply remove the backing of the Velcro strip and adhere -- no tools required!
