U.S. Patrol Alarm Security Bar
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.

Security for Less A good buy for the person who wants a little more security while at home. Easy to assemble; add 9 volt battery and you get either the siren or the barking dog if someone attempts to open the door. Would not recommend the "barking dog" unless you want it to sound like a "barking puppy". Siren is Great!!! January 17, 2013
