ABSTRACT:
This locking bar device enables a person to further secure a door against intruders, when the user is inside of his or her dwelling, and it consists primarily of a pair of brackets installed on the door jambs, that have steel pins, which receive a horizontal bar. The device further includes a key-operated lock, and the structure is such, that it will withstand enormous pressure.
