Abstract: An improved latch guarded door lock and frame system is provided. A recessed surface is provided in a hollow metal frame, and is dimensioned to accommodate a latch guard so that the external surfaces of the door, frame and latch guard are flush. The recessed surface of the frame behind the latch guard is further reinforced by employing a thicker wall than is used in the rest of the frame, and by welding a square metal tube into the recessed region. A medial metal support is also welded into the lock box cavity in order to prevent the lock box from collapsing under stress. The resulting door lock and frame system is less penetrable than prior systems, and provides greater security because the latch guard is less vulnerable to prying and because the frame and lock box are reinforced, thus less likely to collapse under stress.
