Abstract: A reinforcing system for strengthening a door frame having two parallel vertical doorjambs separated from one another by a top horizontal doorjamb. The reinforcing system comprises two elongated channel-shaped 90° corner members positioned in the upper opposite corners of the door frame. Each corner member comprises one elongated flat panel with two substantially parallel sides extending along and outward from the opposite edges of the flat panel. The flat panel has a width and the parallel sides extend in a direction permitting each of the parallel sides to be positioned adjacent one of the opposing sides of a doorjamb when the flat panel is positioned adjacent the exterior side of the doorjamb. The reinforcing system further comprises at least one elongated straight channel-shaped member otherwise similarly formed positioned on the doorjamb opposite where the door hinges will be attached.

Abstract: A reinforcing system for strengthening a door frame having two parallel vertical doorjambs separated from one another by a top horizontal doorjamb is disclosed. The reinforcing system comprises two elongated channel-shaped 90° corner members positioned in the upper opposite corners of a door frame. Each corner member is shaped by one elongated flat panel with two substantially parallel sides extending along and outward from the opposite edges of the flat side. The flat panel has a width and the parallel sides extend in a direction permitting each of the parallel sides to be positioned adjacent one of the opposing sides of a doorjamb when the flat panel is positioned adjacent the interior side of the doorjamb. The reinforcing system further comprises at least one elongated straight channel-shaped member otherwise similarly formed positioned on the doorjamb opposite where the door hinges will be attached.
