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 the L4V Hook Lock fitted high-position on the side load door(s) and the L4V Deadlock fitted mid-position on the rear barn doors.
