ABSTRACT:
A security bar assembly has a plurality of bars that extend across an opening and have ends joined to drive chains to provide an easily removable assembly. The bars extend between two channels positioned on opposite faces of the opening, and are slidable within the channels. The ends of the bars are retained in the channels and the ends have connections to chain links in opposing drive chains which are spaced apart a predetermined number of links to keep the bars a predetermined distance apart. A drive mechanism is provided for moving the drive chains to slide the bars in the channels and a storage area adjacent the opening associated with the channels to retain the bars when they are not in place over the opening.
