Yes there is - I've got one that I ordered to come in with a truck from the States, and the bloody 50mm coupling won't fit onto it!
2" = 50.8mm
But you're right.

When will NZ officially ban 1 7/8'' couplings and change to the international standard 50mm couplings as the UK did some time ago? Becoming highly annoying with many new cars now fitted with sophisticated forged OE 50mm tow balls.

Recently got given a trailer with exactly 'that', a coulping i'd never seen with the large adjustable bolt around the front of it & did rattle it's arse off so wound it up & did the job perfect--well over did it & had to back off 1/4 turn to get it off when i got home. Nice to hear i'm not the only one. Did wonder though if there had been a horse shoe [crescent shape?] piece that had dropped off the bolt.

My towbar has 1 7/8th, 50mm and 70mm balls and a pintle hook and can change between them in 30 seconds.

That might get it on!

Ours has the two usual sizes supplied new with the towbar too.

Yep Acker Bilk--was one of my favourites way back.
Jeez - thanks for reminding me how terrible I was. It was a bugga that my brother left town and took all his instruments with him. Thus ended the pain of trying.

Banning the new sale of 1 7/8'' tow couplings would not pose any problems as existing ones would still be used, and the country would gradually change over to the more universal 50mm types especially with more new imported cars having them, and are much better quality ones.

Not a matter of changing the ball to a bigger size. What about the million trailers around with the small couplings.
