A bolt module is disclosed. The bolt module comprises: a bolt moveable between a thrown position and a retracted position; an anti-thrust member moveable between a release position in which the bolt can be retracted and a plurality of blocking positions obstructing driving back of the bolt under action of an external force on the bolt and, a first rotor assembly capable of accepting a drive element, the first rotor assembly arranged to drive the bolt and to move the anti-thrust member between the plurality of blocking positions and the release position. Each of the plurality of blocking positions may respectively limit to different extents the driving back of the bolt under action of an external force on the bolt. There is also disclosed a leaf or door comprising the bolt module, wherein the bolt module is mounted on the leaf or door for securing the leaf or door.

A door latching system provides an arc resistant door for a power electronics cabinet. The door latching system includes a six point latch to secure the door in place against the frame of the cabinet. The door latching system includes two vertical linkages coupled to a door handle mechanism, the door handle mechanism being able to impart a vertical motion to the vertical linkages as the handle is turned. The latching system allows for this vertical motion to then become horizontal motion for closing several latches between the vertical frame of the cabinet and the door.

A locking system includes a tamper-resistant lock and key. The tamper-resistant lock can include a cylindrical lock body with an upper portion having an engagement surface defining a pattern of engagement features, a housing, and a hidden component sized and shaped to fit within the housing that includes an internal lock base into which the cylindrical lock body fastens and a padlock pin configured to secure the internal lock base to a hasp or staple. The key operable for use with the tamper-resistant lock can include a cylindrical key body defining an engagement cavity configured to receive the engagement surface of the cylindrical lock body, a set of complementary engagement features, a plurality of retractable engagement members, and a retractable collar at least partially covering the cylindrical key body.

A locking system includes a tamper-resistant lock and key. The tamper-resistant lock includes a cylindrical lock body with external threading on at least a portion thereof and a bore extending into an end of the cylindrical lock body. The bore includes an engagement feature disposed on the wall that defines the bore, and the engagement feature is disposed a particular distance away from the bore opening. The key includes a collar that has a cylindrical key body that fits within the bore of the cylindrical lock body. The cylindrical key body also includes an opening defined by the collar sidewall, a retractable engagement member at least partially disposed within the opening, a spring disposed within the collar, and a plunger disposed within the collar that is operable to engage the spring and has a recess sized and shaped to accommodate the retractable engagement member.

An exemplary closure system includes, among other things, a striker assembly, a latch assembly, and a hooked structure. In response to the striker assembly and the latch assembly being laterally displaced from each other, the hooked structure engages one of the striker assembly or the latch assembly to block separation of the striker assembly from the latch assembly. An exemplary latching method includes, among other things, engaging a hooked structure in response to a striker assembly being laterally displaced relative to a latch assembly. The engaging blocks the striker assembly from separating relative to the latch assembly.

The present disclosure is a locking system that has an opening in a door adapted an arranged for receiving a lock bolt and a lock fixed in a wall for actuating a lock bolt adapting and arranged for being received by the opening in the door when the door is closed. The locking system further comprises a blocking strip protruding from a door jamb, the strip coupled to the door jamb and positioned adjacent the lock bolt for blocking access to the lock bolt between the door and the door jamb.

A locking system that has an opening in a door adapted and arranged for receiving a lock bolt and a lock fixed in a wall for actuating a lock bolt adapting and arranged for being received by the opening in the door when the door is closed. Alternatively, the locking system is mounted on the exterior of the detention cell door and the adjacent exterior cell wall. The locking system further comprises a blocking strip protruding from a door jamb, the strip coupled to the door jamb, the strip coupled to the door jamb and positioned adjacent the lock bolt for blocking access to the lock bolt between the door and the door jamb. The locking system further comprises a system for monitoring and reporting the status of a detention cell door, the lock bolt, and the roller bolt.

Disclosed is a door security kit comprising (1) a metallic cuboid compartment, (2) a door guard assembly, and (3) an ASA/ANSI modified strike plate, the modified strike plate constructed with a top notch, a bottom notch, and an elongated lip. The metallic compartment further manifests a rear planar panel, having an adjustable channel cutout. A mortise cylinder mounted externally to one surface of the compartment connects to a tailpiece at one end with a keyway extending therethrough. Rotation of the keyway operates the tailpiece and a connected rod, the rod moving metallic plates to control the size of the adjustable channel. Decreasing the length of the adjustable channel causes the channel to clamp onto the notches of the strike plate, preventing movement of the door bolt from its insertion within the modified strike plate. The door, and the strike plate, are both housed and operate within a doorjamb.

An apparatus is provided for securing together two members which are slidable towards and away from each other to provide a respective open and closed (locked) mode, wherein a plurality of devices are adapted to secure the members in a closed mode, and a control unit is adapted to operate the devices. The devices are in the embodiments described spaced longitudinally apart along a vertical edge or stile of a closure member, which may be a patio door, window, or other closure, with the control unit being disposed intermediate the devices and being operatively linked thereto by a connecting device for actuating the devices. The control unit may be driven manually by a control handle, by a solenoid, by an electric or electro-mechanical motor device, or by spring-loaded interlocking devices. The devices cooperate with keeper devices for securing the closure members together in the closed (locked) mode.

A barrier that includes four structurally different corner connections for fixing a gate frame of the barrier to and between opposing vertical surfaces. A first connection includes a headed straight pin engaging a pivot hook and socket, a second connection includes a headed straight pin engaging a socket, a third connection includes headless bent pin engaging a socket and a limiter, and a fourth connection includes a headless bent pin engaging a socket.
