The dual function door security bar is a strong 20 gauge steel adjustable door brace that installs easily under the door knob and provides added security for your home, business or college dorm room. Adjustable from 30-46 inches.
The Door Brace Prevents the Door from Opening
The steel bar adjusts to fit most hinged doors and one of the rubber end caps can be removed to allow for use on sliding glass doors as well. Clean, baked enamel finish makes this attractive for in-house use.
This door brace is also an effective door locking mechanism you can use while traveling. With the device in place, you don't have to worry about someone opening your door even if they have a key.
Ever been to a motel and all of the sudden you hear someone trying to get in? The desk clerk assigns your room to someone else and gives them a key as well!
They won't get in with the door jammer preventing it. Gives you time to call the front desk or the police if necessary.
Door Security Bar
This is an extra layer of protection and security and is useful for just about any entryway. It can make you not only "feel" safer but actually "be" safer. It would take an awful lot to break in with one of these in place and in doing so would cause an awful lot of noise.
You would have plenty of warning to call the police and arm yourself before they actually got in.
