Coupling Tc40 Suit 50mm — Reliable Snap-Lit Tow Hitch for Tough Australian and NZ Roads

The Coupling Tc40 Suit 50mm from Trojan is built to handle the realities of long-distance touring, caravanning, and light-to-medium towing. With a galvanised finish, this 50mm tow coupling stands up to corrosion from salt, spray, and dirt, so you can rely on it project after project. The integrated anti-rattle screw minimizes hitch noise and unwanted movement, delivering a quieter, smoother tow even on rough roads.

Key features designed for real-world use include a quick, secure snap-lock action that makes hitching up fast and confident, so you can hit the road without unnecessary delays. The 3/4” Master Cylinder included with the unit provides reliable braking control, helping ensure smoother deceleration and safer stops for your trailer or caravan.

Safety and standards matter. The Tc40 Suit 50mm complies with Australian Standard AS4177.3 (1994), giving you peace of mind that the coupling meets recognized safety requirements. It’s rated to a maximum trailer weight of 2500 kg, making it a solid choice for caravans, trailers, boat trailers, and other light-to-medium duty towing tasks. The mounting pattern is designed for NZ-pattern bolt layouts, using four 12mm high-tensile bolts for secure, durable installation. The pattern centers are measured across bolt centers, so you know the fit is correct for your setup.

Who should consider this coupling? Trailers and caravans that need a proven 50mm connection with a dependable snap-lock, users looking for a galvanised solution with effective anti-rattle performance, and installers who require a four-bolt NZ-pattern mounting for frequent use. It’s an excellent choice for those who tow regularly and want a hitch system that stays quiet, aligns precisely, and stands up to the demands of the road.

Practical tips for optimal performance and longevity: ensure the mounting surface is level and clean, verify the NZ bolt pattern matches your setup, and use four 12mm high-tensile bolts for installation. Periodically inspect the anti-rattle screw and the master cylinder for signs of wear, and service them as part of routine trailer maintenance. With proper installation and care, the Tc40 Suit 50mm delivers consistent braking control, reduced wear, and dependable operation trip after trip.
