Compatibility and Fitment

The Wallace Forge R51A Towing Eye connects to a compatible heavy-duty pintle hook that accommodates a 3″ eye and 1 5/8″ ring section. Unlike a conventional towball coupling, the ring engages directly with the pintle hook and its locking mechanism.

Before fitting, compare the four mounting holes with the existing 4 1/2″ square pattern. Check the nose plate thickness, mounting hardware and available clearance for ring movement.

The coupling requires a mounting arrangement capable of carrying the intended towing and vertical loads. Confirm the complete towing combination rating rather than relying on the towing eye capacity alone.

Compliance and Safety

The R51A carries Australian approval reference CTA-016130. Confirm that the vehicle, drawbar, mounting structure and pintle hook meet the required ratings for the intended towing application.

Wallace Forge advises against welding or modifying its bolt-on towing rings. The manufacturer also warns against using pintle hooks that restrict ring movement or rotation, including unsuitable fish-mouth style hooks.

Inspect the towing eye for wear, cracks and deformation. Check the mounting hardware and pintle hook condition before towing.

Trailer Applications

The four-bolt towing eye suits heavy trailer drawbars and compatible pintle hook towing arrangements. Applications include commercial trailers, agricultural equipment and heavy transport combinations where the coupling and mounting design meet the required loads.
