The Deadlock is a mechanical deadlock for vans operating independently from the manufacturers’ locking system. It is very similar to the Hook Lock however this lock engages a ‘straight bolt’ (20mm-50mm) 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. The Deadlock is recommended for use on the vehicles cab doors.
