ABSTRACT:
Apparatus for securing a window or door that has a slidable sash includes a grille that has a set of spaced parallel bars that extend in the direction of motion of the slidable sash. The grille fits into the frame of the window and is secured there by a locking bar or other means. A flange on the slidable sash includes holes through which the bars pass as the sash is moved. The flange is captive on the bars and serves to prevent an intruder from pushing the grille into the room from the outside. The grille can be quickly removed from inside the building by an occupant who must flee in the event of fire or other emergency.
