Tow hitch requirements

[CAPP0]

Because of what I need to tow, I have a hitch on the car which is the combination 50mm ball with a pin & jaw below it, like this:



I believe there is a difference between and industrial/agricultural/offroad hitch, and one used on the road, and I *think* that difference is that the pin has to have two retaining clips for road use, as opposed to one for other use. Anyone know if that's correct, or advise me? Google hasn't turned much up so far.

Maybe contact a manufacturer or company that fits them.

Mine is a Witter so maybe give them a call.

I've never heard that, or seen one with 2 pin retaining clips, but the type you have pictured is the type sold by motorfactors, towing websites etc so I'd assume it's road spec.

The only slight variation I've seen are those where the pin passes through the centre of the tow ball. These are weaker and I'd recommend sticking to the type you have pictured.

The odd thing is, I have both types! One which I bought for one vehicle, the other which came with the tow hitch on the other vehicle! One definitely has both an R clip and one of those sprung circular clips, at the bottom of the pin and at right angles to each other - hence my query/confusion!
