ABSTRACT:
A security bar system for use on both "inward" and "outward" opening doors that provides security by preventing forcible entry. The system preferably comprises an elongated, telescoping, bar arranged to extend horizontally across and adjacent to a pair of double doors. Inward opening doors are secured by mounting the security bar on opposing hinges, modified by incorporating docking ferrules into which right angle mounting dowels existing at each end of the reinforcing bar can be securely inserted, effectively barricading the doors closed. For outward opening double doors, where the hinge pins are typically located on the outside, door jamb mounting brackets in lieu of hinge mounted docking ferrules, are securely fastened to both sides of the door jamb material on the interior at approximately the same height as the door knobs. To secure outward opening doors, the security bar is mounted on the mounting brackets and equipped with an adjustable sleeve that, when properly positioned, engages both door knobs securing them to the security bar.
