The present latch apparatus includes a swinging piece having first and second independent latches or sliders sliding in first and second slots. The first and second sliders slide independently of each other. The first and second sliders engage an undersurface of an extension of a first object such as a gate. If either the first or second slider is engaged on the undersurface, the swinging piece is locked and is not swingable such that the first object such as the gate cannot itself swing away from a second object such as a barrier section. Only when each of the first and second sliders has been slid beyond the undersurface can the swinging piece swing to permit the first object such as the gate to be released and thus swingable itself relative to the second object such as the barrier section.

A locking system includes a lockcase which can be embedded within a recess in a jamb of a doorway. A barn door mounted outside of the doorway can be locked in the closed position by actuation of a lock mechanism within the lockcase. The handle interacts with the lockcase, causing a bolt to be translated out of the lockcase and into a strike in the barn door. The strike preferably passes entirely through the barn door, the strike including an outer entry which can be accessed via a key to push back the bolt and defeat the lock for emergency access. Cover plates and handles of different types can be provided for optimal performance. Lock mechanisms within the lockcase convert handle actuation into bolt translation between a collapsed orientation and a deployed orientation for locking the barn door.

A safe locking system that provides a means to operate one of two (or more) safe locks of any type to facilitate safe opening of a door. The safe door can be opened by operating either of two locks, regardless of the type or style; e.g., e-locks and mechanical locks. A sliding bar assembly is mounted to the rear face of the safe door for displacing the boltwork into and out of the door frame. Extension of the lock bolts of both locks prevents movement of a main locking bar and attached boltwork, which prevents a user from opening the door. Retraction of either of the lock bolts permits sliding movement of the main locking bar, such that a user can unlock the door from the frame.
