DO35 Coupling Lock by Cruisemaster
The DO35 Coupling Lock: the ultimate solution for securing your off-road camper or caravan when you’re away. Engineered with a robust locking mechanism, this product ensures your peace of mind.
Thieves can easily acquire a replacement pin for just $80, allowing them to attach your DO35 coupling swiftly and silently: don’t let your valuable equipment be an easy target.
The Cruisemaster Generation 2 Lock assembly consists of a steel dummy pin, two keys, a lock, and a dust cover.
While no lock can completely eliminate the risk of theft, they certainly act as a significant deterrent, making it more challenging for would-be criminals to take your belongings.
Enhance your security further by considering a hitch pin lock to replace the hitch pin on your receiver bar.
Note: The DO35 Lock: Bi-Lock is designed for use with the DO35 V2, DO35 V3, DO35 V3Plus, and DO45 V1. This lock is not compatible with DO45Plus models.
Kit Includes
- 1 x Dummy Pin
- 1 x Lock Chamber and Dust Cover

How does the Cruisemaster DO35 Lock Work?
- The dummy pin is to be inserted into the DO35 universal joint from the top end. The tip of the pin will protrude out the bottom.
- The lock is then fitted to the protruding end of the pin and locked with the key.
- The coupling becomes inoperable, preventing others from being able to hitch up to your trailer or van when you are not there.
