The door frame is secured to the kennel body at an opening. The door is moveable between an open and a closed position. The door includes a first latch having a first latch bolt engaging the door frame at a first latch location. The door also includes a second latch having a second latch bolt engaging the door frame at a second latch location. The door also includes a third latch having a third latch bolt engaging the door frame at a third latch location. In some embodiments, the first latch bolt extends horizontally toward the door frame, and the second and third latch bolts extend substantially vertically from the door toward the door frame in opposite directions.

A lockable latch handle assembly for enclosures such as truck tool boxes comprises the combination of a key cylinder, and a latch handle that may be secured by a padlock to the front wall of the box, to collectively prevent opening of latches that secure the lid of the box in a closed position.

A package securing system is disclosed suitable for large and small packages and envelopes. Said package securing system comprises a container into which a user would place items to be secured, and a peg or post onto which the user would place the container. Sliding the container past a flange on the peg causes the container to be locked onto the peg. A user may then operate an unlocking mechanism to remove the barrier to removal. The disclosed package securing system is easy to use prompting adoption by delivery persons.

A concealed anti-tamper device to prevent unauthorized opening and tampering with a manufactured product includes a shell, an anti-dismantling structure concealed in the shell, and at least one key. The shell defines a through hole and a slot. The anti-dismantling structure includes anti-dismantling hook module with hook, driving module, and resetting component anti-dismantling hook module. The anti-dismantling hook module is movable within the shell, and when the product is to be locked, the separate key rotates the driving module, which drives the hook of the anti-dismantling hook module to embed in the slot. The key is rotated in the opposite direction to unlock, until the driving module separates from the anti-dismantling hook module, and the resetting component separates the hook from the slot by the restoring force of a spring.
