The combination of a standardized Tc40 mounting pattern, a strong 50 mm interface, and a substantial 2500 kg load rating means you’re choosing a component that stands up to daily wear, weather exposure, and frequent coupling/uncoupling cycles. The four high-tensile bolts specification not only simplifies installation, but also reinforces secure attachment in demanding operating conditions.

Installation tips for reliable performance

• Use four 12 mm high-tensile bolts to secure the coupling, ensuring bolt centers align precisely with the Tc40 pattern.
• Follow AS4177.3 guidelines for mounting torque and fit to achieve optimal clamping and safety.
• Inspect bolts and mounting surfaces regularly for signs of wear, corrosion, or loosening, and re-torque as needed.

Maintenance and reliability

Regular inspection is key to long-term performance. Check for corrosion on the mounting hardware, verify bolt torque, and look for any elongation or deformation in the Tc40 pattern. A proactive maintenance routine keeps downtime low and helps ensure consistent towing performance across seasons and workloads.
