Tow Balls

Shop Heavy-Duty Tow Balls & Towing Equipment

Browse our engineering-grade selection of compliant Caravan and Trailer Tow Balls, manufactured in sizes ranging from the standard 50mm up to commercial-grade 3-inch truck balls. Engineered by Couplemate™ to meet stringent Australian design requirements, these high-tensile fasteners match specific trailer weights, D-values, and V-values. Ensure structural on-road safety with verified, locally tested equipment built to completely mitigate the failure risks associated with non-compliant alternatives.

Compliant Towing Solutions Engineered for Australian Conditions

Tow balls connect varying trailer masses directly to the tow vehicle. While the 50mm ball remains the baseline standard for domestic towing across Australia, growing transport loads require larger, heavy-duty configurations. To address the market demand for guaranteed compliance, Couplemate™ designs, manufactures, and tests its complete range of towing hardware under strict quality controls.

A critical industry concern involves non-compliant, low-quality imported tow balls that routinely fail the mandatory Australian Standard test procedures. Relying on unverified gear risks severe on-road failure, costly legal penalties, and total loss of corporate reputation. Couplemate™ hardware delivers verified physical strength to protect your fleet, family, and equipment.

Regulatory Bulletins & Engineering Frameworks

All safety-critical trailer components and mechanical couplings deployed on public Australian roads must comply strictly with national transport legislation and loading safety parameters:

• AS 4177.2—2004 Mechanical Standards: Under this strict Australian Standard, 50mm tow balls must withstand a maximum destructive force application of 85kN for a minimum duration of 10 seconds. Read more about safety-critical mechanical connection rules on the Australian Vehicle Standards Bulletin 1 (VSB1).
• Review national heavy vehicle compliance frameworks and structural safety parameters outlined by the National Transport Commission (NTC).
• Consult the official portal for Standards Australia to buy or review complete fastener, hitching, and ball connection regulations (AS 4177 series).
