The L4V Hook Lock is a mechanical deadlock operating independently from the manufacturers’ locking system. A deadlocking hook bolt engages into its opposing body section. … Suitable for owner-drivers or applications where the driver can be relied upon to operate the lock.
The key serves as a security token for access to the locked area; locks are meant to only allow persons having the correct key to open it and gain access. In more complex mechanical lock/key systems, two different keys, one of which is known as the master key, serve to open the lock.
