Coupling Overide Less B/f 17/8 — Trojan 50mm Bolt-On Braked Coupling

Introducing the Coupling Overide Less B/f 17/8 from Trojan, a rugged, bolt-mounted coupling engineered for dependable performance in New Zealand applications. Built around one of the country’s most common bolt mounting patterns, this unit uses a 50mm center-to-center arrangement to ensure broad compatibility with receivers and frames across trailers and vehicles.

Designed to handle demanding loads, the coupling is rated to a maximum of 2500 kg. Installation is straightforward: four 12mm high-tensile bolts provide a secure, durable mounting that stands up to frequent use and harsh conditions.

Highlights include:

• Mounting pattern: 50mm across bolt centers (a widely used NZ standard)
• Rated capacity: up to 2500 kg maximum
• Mounting hardware: four 12mm high-tensile bolts recommended for secure installation
• Compliance: Australian Standard AS4177.3 (1994) for safety and interoperability

The 50mm bolt pattern’s ubiquity means faster sourcing, easier replacements, and reduced downtime when servicing equipment. The four high-tensile bolts distribute the load effectively to maintain alignment and minimize wear. Compliance with AS4177.3 (1994) adds a layer of safety and interoperability across different rigs and environments.

Ideal for trailer and vehicle-mounted applications where a standard, widely-supported bolt pattern is essential, this coupling also suits agricultural equipment and light-industrial setups requiring reliable coupling connections. Service teams and workshops will appreciate readily available parts that align with regional standards.

Installation & maintenance tips: Ensure the mounting surface is clean and free of debris before installation. Align the bolt holes precisely, and use four high-tensile 12mm bolts as recommended. Periodically inspect the bolts and mounting surface for signs of wear, corrosion, or loosening, and replace components showing degradation. When in doubt, follow standard high-tensile bolt installation practices and refer to regional guidelines to maintain optimal performance.

Why Trojan: Trojan engineering brings decades of trailer and towing component expertise to reliable mounting solutions, delivering durability and dependable performance in NZ conditions.
