Ensure the safety of your camper or caravan when you're not there with the ultimate coupling lock.
The HITCHMASTER® Bi-Lock assembly consists of a dummy pin, two keys, a lock and a dust cover. Its components are made of stainless steel.
How does it work? The dummy pin is to be inserted into the DO35 & DO45 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.
