Door Stop Security Alarm

Great when setting up and closing down your open houses. Simply place the alarm behind any door. If an intruder attempts to open the door, the wedge-shaped design will both prevent it from opening and activate a 120 dB alarm. The alarm will scare off a would-be intruder and alert you to the attempted entry. The on/off switch will allow the unit to be used in either mode and prevent the unit from accidentally sounding.
