ABSTRACT OF THE DISCLOSURE Two tubular straight frame members, of identical rectangular cross-section, are adapted to be secured to opposite parallel sides of a building aperture and a rigid rod is insertable at both ends into rod-receiving holes made in the inwardly-facing walls of said frame members to extend across the aperture. This inwardly-facing wall, and also the front wall of each frame member, is provided with a pair of screwdriver-receiving holes made on either side of the rod-receiving hole. The two remaining walls of each frame member are provided with screw- receiving holes in respective axial alignment with the screwdriver- receiving holes. Thus, the frame members can be selectively fastened to the transverse or to the outwardly-facing surfaces of the aperture sides. In an alternative embodiment, one frame member is hingedly secured to one side of the aperture, while the opposite frame member is provided with a locking device, whereby the entire grille can be swung outwardly of the aperture.
