An exemplary ring lock generally includes a housing, a shackle, a lock cylinder, and a first frangible component. The shackle is movable relative to the housing between an open position and a closed position. The lock cylinder is operable to maintain the shackle in the closed position, and is selectively operable to permit movement of the shackle from the closed position to the open position. The first frangible component is configured to break in response to application of a first threshold torque to the lock cylinder. With the first frangible component broken, the lock cylinder is prevented from permitting movement of the shackle from the closed position to the open position.

Ring lock with relocking

An exemplary security apparatus generally includes a tether, a head, and a body. The head is secured to the tether, and generally includes a plug including a latch and an actuator at least selectively operable to move the latch from a latching position to an unlatching position. The body is secured to the tether, and includes a port operable to receive the plug. With the plug received in the port, the latch prevents separation of the head and the body when the latch is in the latching position, and does not prevent separation of the head and the body when the latch is in the unlatching position.

Portable lock apparatus

An exemplary lock apparatus generally includes a shackle, a crossbar, a lock device, a first bolt, and a trigger. The lock device has a locked state in which the lock device retains a spindle in a spindle locking position, and an unlocked state in which the lock device does not prevent movement of the spindle to a spindle unlocking position. The first bolt is engaged with the spindle such that movement of the spindle between the spindle locking position and the spindle unlocking position drives the first bolt between a first locking position and a first unlocking position. The trigger is movably mounted in the crossbar for movement between an engagement position, in which the trigger maintains the spindle in the spindle unlocking position, and a disengagement position, in which the spindle is operable to move to the spindle locking position.
