An extendable security bar assembly, is convenient, and more aesthetic than existing security bar systems, and is used primarily for security. The assembly is for placing over or in an opening and has a plurality of bars extending between two channels, the two channels positioned on opposing faces of the opening with the bars slidable within the channels. The bars are connected at each end within the channels to a transporting mechanism in each channel coordinated to slide the bars across the opening. A drive system is provided for the transporting mechanism, and guides at ends of the channels guide and retain the bars in a storage area substantially adjacent the opening. The channels may each enclose a drive mechanism for independently moving the bar ends in each channel. In such embodiments, each channel may be associated with a separate motor or drive mechanism, and the drive mechanism in each channel may be independently driven by a separate motor. The separate motors or drive mechanisms may be connected for synchronisation by a non- mechanical communication link.
