Secure your home from intruders with this security device, which alerts you to an intrusion with sound that also surprises possible intruders, while barring your door from entry. The heavy gauge steel tension bar wedges between the underside of the doorknob and the floor. This prevents the door from opening from the other side, and when the doorknob is touched an alarm sounds. You can even choose between a powerful siren sound or barking dogs. Bar extends from 29" to 43" to fit any door. Requires one 9-volt battery, not included.
