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. Operated by its high-security external key under full control of the driver. Suitable for owner-drivers or applications where the driver can be relied upon to operate the lock.
Recommended Fitting Position
We recommend an L4V Hook lock fitted high in the side load door and a L4V Hook lock fitted in the high position on the rear barn doors.
