Estate Tow Bar Question

[waspy]

This is my tow bar arrangement



My question is- is this bar (below) that fits under the car behind the tank solid or hollow box section?
The reason I ask is because the one above is solid & weighs quite a few kilo & if this one's also solid then the extra weight will be just silly

Its hollow box as far as I am aware,If it was all solid bar it would weigh as much as the car

I'm a steel fabricator by trade & I've worked on solid bar this thick & it would weigh a stupid amount which is why I'm asking

All the ones I've come across are hollow box section Pete.

Its hollow without a doubt

We're all saying hollow & that'll do for me

Thanks chaps

I don't really wana take it off for now & the fact that it's hollow allows me to leave it on. Other wise it would be getting changed for another of less weight
