Help make your door "intrusion-proof" in seconds with this battery-operated door alarm.
For hinged doors, a forced opening is virtually impossible when this security bar is wedged under the knob. And when the outer knob is touched or the door is pushed, it sounds a loud alarm or dog-barking sound (your choice) for five seconds; resets automatically.
This door security bar is made of heavy-gauge, carbon steel and adjusts from 29" to 43" long. The Door-Jamming Alarm Security Bar works on carpet, tile or wood floors. And since this security alarm is portable, you can take it with you to your summer home, hotel room, or anywhere you feel the need for added security. The door alarm requires one 9v battery, sold separately.
