DO35 Coupling Lock Ensure the safety of your camper or caravan when you're not there with Cruisemaster's own DO35 lock. Gen.2 DO35 Lock at all new lower price! The Cruisemaster™ DO35 Lock assembly consists of a dummy pin, two keys and lock chamber with 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. This product is covered by a 12 Month Manufacturers Warranty. IMPORTANT: Lock is suitable for All Versions of DO35 & DO45 V1 Only Not suitable for DO45Plus
