Who doesn´t know this: Sitting on the toilet feeling undisturbed. Suddenly the door opens. The problem: Until now cubicle handles just show from the outside if it´s busy. But not from the inside – therefore visitors can not be quite sure if they have really locked the door.
The solution: INSAFE comes as first handle with a red-white viewing window also on the cubicle inside. Therefore awkward surprises certainly won’t happen.
