Best Caravan Tow Ball Lock

Last Updated on February 4, 2023 by Leepu Da Maxim

Sam’s trailer is sitting right behind the RV pad. He’s been driving the whole day, and now, he wants to rest. So he turns in early because tomorrow, he’ll be on the road again. But when he wakes up, his trailer is missing.

What just happened?

Caravan theft is a significant issue in countries where RVs are popular. In Australia, for example, insurance companies report over 500 stolen caravan cases every year. Sadly, most of them remain undiscovered and unrecovered.

But things can be different if you invest in a locking product. That’s because manufacturers have special caravan tow ball locks to help guard trailers. In this article, we bring you seven of the best ball locks.
But before we do, here’s a brief explanation of what those locks are.

What Is A Caravan Tow Ball Lock?

A tow ball lock is a protective item that prevents someone from hooking and taking off with your caravan. It is small-sized, easy to carry, and you can use it on different trailer types.

Other names of the tow ball lock include coupling lock and tongue lock.

How Does A Caravan Tow Ball Lock Work?

To secure your caravan, the ball-like item goes over the coupling and locks in. Then, when you turn the key, the lock remains in place such that no one can attach it.

Here’s an image of how the locking happens:

How To Pick The Best Caravan Tow Ball Lock

As you buy, consider the following factors:

1. Fitment (fitting). Some ball locks have a universal fit, but others are specific to some couplers. So, check your trailer’s tongue size and have that detail in your mind.

2. Material. It is best to have a heavy-duty steel or aluminum lock. Those materials are robust, and breaking them would prove difficult for anyone. Also, they are rust-resistant, which makes for a long-lasting item.
