ABSTRACT:
A security device for securing a hinged door against forcible opening is disclosed. The apparatus includes an interior plate portion secured to an inner side of the door frame. The interior plate portion defines a first edge disposable in a gap between a latch edge of the door and a latch receiving portion of the door frame. When installed in a door apparatus, the security device prevents the door from being forcibly opened even if the latch receiving portion of the door frame is damaged or the door is bowed or bent inward. An alternative embodiment of the security device includes a latch plate reinforcing portion and a clamping portion in addition to the interior plate portion. A kit is disclosed that includes the interior plate portion and screws for attaching the interior plate portion to the door frame and for reinforcing the door hinge.
