Disclosed herein is a panelboard guard assembly configured to restrict access to a panelboard having a cover and a door defined therein, the cover having first and second side edges. The panelboard guard assembly includes overlapping members that are, at least in some implementations, mutually coupled to each other. The panelboard guard assembly further includes an adjustment mechanism that extends between and couples the members together, the adjustment mechanism facilitating adjustment of the distance between the outer ends of the members.

An improvement for use with a door latch assembly for a roll-up door includes a shim dimensioned and shaped to be positioned over a latch cover of the latch door assembly and to be slidingly moved to a shim extended position wherein a shim tang extends beyond a latch slide tang of the latch assembly. The shim is configured so that, if the latch assembly is mounted to a rolling door and is locked into an unsecured position by a first lock, wherein the slide tang does not engage the door jamb, the shim can be moved to and locked in the shim extended position to secure the rolling door without removing the first lock.

Disclosed is a door securing apparatus. The door securing apparatus includes a base member, a pivoting arm extension, and a door-contacting member that act in concert to secure a door in a closed position.

A defense mobile device for securing a door during shelter-in-place situations. The device includes wheels rendering it mobile and stops that, when activated, hold the device stationary. A panel has a ballistic core that resists bullets, a front face, an opening, and a cover positioned over the opening to overlay and enclose a door knob protruding through the opening. The front face forms, or has affixed to it, a writing surface. The panel pivots between a plurality of angled positions to facilitate writing and an upright position flat against the door. A locking rod, rotatably connected to the panel, pushes and pulls the panel between its angled positions and its upright position. A portal defined by a ballistic door viewer or viewport is located in the panel and permits viewing or observing through the panel. A release system is configured to deactivate the stop and enable the device to move.

A door locking device includes a mounting plate configured to be mounted to the door; a reinforcement gusset extending outward from the mounting plate, the reinforcement gusset defining an extension portion; and a wall engagement member adjustably affixed to the extension portion of the reinforcement gusset and laterally offset from the mounting plate; wherein the wall engagement member is movable relative to the extension portion in a direction substantially perpendicular to the mounting plate, and wherein the extension portion is configured to confront a wall adjacent to the door.

The emergency egress apparatus includes a protuberance mated to a first portion of the door barricade and a keeper mated to a second portion of the door barricade. A retainer is selectively disposed between one of two positions. A first position defines the placement of the retainer that establishes an interference fit between the protuberance and the keeper. A second position defines the placement of the retainer such that it is not in contact with the protuberance or the keeper. The first position secures the first portion of the door barricaded with respect to the second portion of the door barricade, and the second position decouples the first portion of the door barricade with respect to the second portion of the door barricade

A door security device has a rail support including a top surface and a bottom surface. A door support is attached to the rail support, such that the door support extends vertically away from the rail support of the door security device. The door support is oriented at a normal relative to the rail support. The bottom surface of the rail support rests parallel to a surface of a rail of a crash bar when the bottom surface is situated adjacent the surface of the rail. The security device creates a rigid connection to prevent unwanted removal of the door from a closed position.

A double door assembly bottom restraining device and method provide stability to the double door assembly during manufacturing and shipping. The double door assembly bottom restraining device may be installed on the bottom of a double door assembly.

Embodiments disclosed herein relate to secure storage boxes having a lock post bracket attached to a lid of the secure storage box and a lock body bracket attached to a body portion of the secure storage box. The lost post bracket may be constructed to retain a lock post, and the lock body bracket may be constructed to retain a lock body. The lock body may include an opening configured to selectively retain the lock post when the lid of the secure storage box is closed. Thus, the lock body may prevent the lid of the secure storage box from opening by retaining the lock post. Moreover, the lock post bracket and the lock body bracket may include features for confirming the alignment of the lock post to the opening in the lock body. For example, the lock post bracket may include two or more hollow cylinders configured to register with two or more complementary pins disposed on the lock body bracket. Moreover, the lock body and lock body bracket may a complementary interface for confirming that a compatible lock body has been installed with the lock body bracket.
