Door Stopper Alarm Device

Let's be sure to keep the doors lock. If you do not have a lock, this is a wedge-shaped design of an electronic device that will stop your door from being opened and set off a 120 dB alarm if attempted. The stopper works best when the floor and the bottom of the door are less than 1 inch apart. The on/off switch will prevent the unit from accidentally sounding. Features: Great for Home or Travel 3 sensitivity modes: high, medium, low Innovative Door Security
