Abstract

A window bar guard system for discouraging breaking and entry through a window is constructed of components which may be readily assembled and installed by the consumer. The grillwork for the window bar guard system includes a set of telescoping tubular steel bars. The telescoping bars permit the consumer to expand or retract the grillwork system to fit a desired window. Upon obtaining the proper size of the grillwork, the steel tubular bars are permanently secured together to provide a solid grillwork custom fitted for the particular window.
