ABSTRACT:
A door security apparatus and method that is adapted to assist in retaining a pair of adjacent doors in a closed state, thereby to help protect against unauthorized opening of the doors by placing the doors into an open state. The door security apparatus includes a channeled extension beam having a longitudinal axis, the beam is adapted to fit over and removably engage a pair of adjacent door edges that are in the closed state and a mechanism for manually selectively rotatably clamping or unclamping the beam to at least one door edge. Wherein the doors have increased protection against unauthorized opening, thus placing the doors into a more secured closed state, the mechanism only manually selectively clamping or unclamping the beam from the door edge by applying a manual external force in conjunction with manual forward or manual reverse rotation.
