Abstract

A security bar providing improved security from breach is obtained with the use of a plurality of free rolling inner bars. Illustratively, three inner rolling bars, arranged in a triangular relationship, are provided inside a cylindrically hollowed out outer bar, thereby ensuring that no inner bar can be attacked simultaneously from opposing sides thereof. The inner bars may be surrounded with a ring of ball bearings to provide for their ability to roll freely in place with respect to the outer bar. Electronic monitoring of the security bar identifies attempts to breach the security bar.
