ABSTRACT:
A safeguard system is provided to prevent unauthorized entry through an open window of a casement in which said window is vertically positionable. The system involves a barrier apparatus comprised of two framed gridwork panels in horizontally spaced coplanar juxtaposition. The spacing between the frames is adjusted by a coupling pin which insertively engages matching apertures in an extension arm and a horizontal border of a frame. A locking device is provided to prevent vertical movement of the window away from engagement with the barrier device.
