Helps Stop Intruder & Sounds Alarm. Ideal for hotel, motel, home and collage dorm. Wedge alert is so simple to use and yet so effective. First place it on the floor close enough to keep the door from being forced open. When an intruder tries to come in, its wedge design prevents the door from moving and sounds a piercing 120Db alarm. If the unit is moved or pushed away from the door with an object from the other side, the device will also sound an alarm. It uses a 9- volt battery (not included).
