What is a ball coupling? We explain what a ball coupling is, what designs they come in and what is important to think about them.
A ball coupling is the part of a trailer that is connected to the towbar of the car. The towbar of the car is located on the tow ball, and it wears out during use. Ball couplings come in either 50mm or 60mm and are divided into different weight classes. It is therefore important to ensure that the ball coupling can support the weight for which it will be used.
