As a result of growing demand, Couplemate commenced the manufacture of all ball sizes. Our largest truck ball size is 3″ for our 10t gooseneck coupling.

We also found many Chinese balls do not pass AS4177.2. Therefore, compliance standards are not met; as a result, strict penalties and loss of reputation for offending companies are costly.

To ensure compliance with the regulations, Couplemate manufacturers and tests our towing equipment.
