Tow Ball Scales, How Do They Work?
Tow ball weight scales suit standard 50mm couplings and ensure an accurate weight reading so you can balance your load easily and safely without any guesswork or damaged towing components.
What is tow ball weight and why do I need to measure it? When loading up your trailer or caravan, most of the weight is supported by the trailer's suspension, however, some of the weight is applied to the trailer coupling, tow ball, tow bar and chassis of the car. This weight at the coupling is known as tow ball weight. Tow ball weight varies every time you load your trailer, being higher with more weight at the front of the trailer or lower with more weight at the back. Trailers that are too heavy in the rear are also susceptible to dangerous handling characteristics and swaying, so balancing this weight is imperative as towing setups carry a maximum ball weight limit which cannot be exceeded for legality and safety reasons.
