Abstract: The invention is a special bar assembly that could be easily installed on a steel door of a commercial building. The invention comprises a permanent door piece, door mounting hardware, and a lock piece assembly. The secure bar when in a locked position will keep the door from opening by impacting the door jam of the door that it is attached too. To unlock the secure bar simply detach and remove the lock piece assembly. A second embodiment of the secure bar enjoys all the same parts, and features with the exception of a longer lock piece for use on a double-door configuration.
