Ensure the safety of your camper or caravan when you’re not there with Cruisemaster’s own DO35 lock.
The Cruisemaster™ Bi-Lock assembly consists of a steel dummy pin, two keys, a lock and a dust cover.
How does it work? The dummy pin is to be inserted into the DO35 universal joint from the top end and the tip of the pin will protrude out at the bottom. The lock is then fitted to the protruding end of the pin and can be locked with a key. The coupling becomes inoperable which prevents others being able to hitch up to your trailer or van when your not there.
IMPORTANT: Lock is suitable for use with DO35 V2, DO35 V3, DO35 V3Plus & DO45 V1 Only
Not suitable for DO45Plus
