The Ark 2 Hole Coupling 50mm 2000kg hooks a trailer or van to a standard 50 mm tow ball and keeps it there over long bitumen runs and graded dirt. A quick release latch with adjustable screw lets you tighten ball fit by a few millimetres so the head does not rattle when you are rolling with up to 2000 kg on the drawbar. A padlock point adds basic security when you park up at a servo or campsite.

Cast steel construction and a plated finish mean this coupling stands up to stone spray and wet roads over season after season. The two hole mount lines up with typical Australian trailer drawbar plates so swapping an old head for this one is straightforward. Compliance with AS4177.3 – 2004 keeps the gear within local towing standards. If you tow work trailers or weekend campers, this is a smart buy that is built tough for Aussie conditions.

Q: What tow ball size does this Ark coupling suit?

This coupling is made for a 50mm tow ball only. Using it with the correct ball size keeps the latch seated properly under load. A smaller ball can let the head rattle or disconnect. A larger ball will not seat and can stop the latch from closing fully.

Q: Can I lock the trailer to the tow vehicle with this coupling?

Yes, the coupling includes a padlock facility. You can place a suitable padlock through the built-in tab once the latch is closed. This helps deter casual theft when parked. It also stops someone from opening the latch without removing the lock first.

Q: Is this coupling rated for off-road use?

The coupling is listed as a road coupling with a 2000kg rating. It is intended for standard road towing on caravans and trailers. For heavy off-road articulation or rough tracks, many setups use off-road specific couplings. Match this gear to road-biased touring or work use.

Q: Does this coupling meet Australian towing standards?

Yes, the coupling complies with AS4177.3 – 2004. That standard covers mechanical requirements for 50mm ball couplings used on light trailers. Compliance indicates the design has been assessed against strength and performance criteria. This helps you match the coupling to legal requirements in Australia.
