Installation & usage tips

Prepare the mounting surface to be clean and flat, then align the Tc40 drawbar so the four bolts sit squarely. Use four 12 mm high-tensile bolts as specified to achieve the intended strength and torque stability. Always verify compatibility with your trailer’s drawbar and ensure the total GVW stays within the 2500 kg max rating. Periodically inspect the mounting hardware for signs of wear or loosening and re-torque bolts as part of your routine maintenance.
