  • Metal window construction
    Patent number: 5155956
    Abstract: A metal subframe is anchored into an opening in a building wall as the wall is being built. A factory-glazed and factory-welded metal frame is snapped into the subframe conveniently from inside of the building. integral one-way clips or latches automatically align, center and permanently capture the frame as it is installed in the subframe, and no field welding is thus required. The latches are internal and inaccessible when locked, thereby making this metal window construction well suited for security installations.
