Description
Window AKKA allows ventilation even in rough weather. Suitable for almost all windows from the 18th century to the 1950s, where the outer window opens outwards. Installation takes less than 3 seconds! You can export AKKA from window to window, so you don't have to get them for each window. Open the outer window and put the AKKA loop in the frame tail hook and taper the end to the finger hook at the attachment point.
