50mm Tow Ball
A 50mm tow ball is a standard towing component, widely used for trailers, caravans, and boats with an Aggregate Trailer Mass (ATM) of 3,500kg or less.
Core Technical Specification
- Ball Diameter: Exactly 50mm.
- Towing Capacity: Most high-quality 50mm tow balls are rated at 3,500kg.
- Vertical Load (Ball Weight): Typically rated to handle a downward pressure (ball weight) of 350kg.
- Shank Dimensions: Standard shank diameter is 7/8 inch (approx. 22mm). Shank lengths vary from standard (approx. 50-52mm) to extra-long (62mm or more) to accommodate bike racks or thicker mounting plates.
- Material; Finish: Usually made from forged or high-tensile steel. Standard finishes include chrome plating, zinc plating, or black powder coating for corrosion resistance.
Tested and Compliant with AS4177.2, Caravan and light trailer towing components.
One of the most straightforward and practical tow hitch options, the 50mm tow ball provides good swivelling and fastening performance.
Typically, you’d mount the tow ball onto the chassis of your tow bar to pull your trailer or caravan.
Tow Ball Hitches and Receiver Kits
Necessary: We recommend that all off-road couplings, regardless of brand, use a solid cast receiver hitch. Open receivers have a welded tongue that deforms under extreme off-road conditions and during shock-loading events on the highway.
Couplemate manufactures a range of cast tow bar receivers and hitches in Australia and tests them to Australian road conditions.

- 22mm Diameter
Testing
All trailer connections must be tested in accordance with the Motor Vehicle Act of 2018. Couplemate tow balls are tested to comply with AS4771.2.
3500kg tow balls meet the minimum force requirement of 8667.59kg as specified in the Australian Standards.

- Markings: Compliant balls must be stamped with the manufacturer’s name, the “50” size mark, and the rated capacity.
- Installation: Most come with a spring washer and high-tensile nut. Correct torque (often specified around 225Nm to 300Nm, depending on the brand) is critical for safety
