Adding a roof box to a trailer
Discussion
I have this trailer and a roof box, I’d like to make the raised frame to house the roof box and maybe a bike rack
What buzz words do I need to help narrow it down and what are the black brackets
Also what would the (presumably) collars for the bolts to give the clearance be called?
This is a picture from eBay
Many thanks

If you are going to load it up something like brenderup 1205 will run better with the bigger wheels. You can get fibreglass tops or cage or solid sides as well. Unless you already have the bits would just buy a 2nd hand one ready to go.
You are probably right, at the moment I’m trying to minimise expenditure so would prefer to knock something upSpare tyre said:
That whole arrangement is DIY'd. Someone has drilled additional holes in a set of standard roof bars, and the trailer sides, then used a bunch of bolts and washers to put it all together.Neatly done, but not thought about the loads that will be under. IMO not safe.
Here's how the factory bars are done - attached to the top rail of the trailer sides, and the load is carried much closer to the fixing point to prevent them acting as massive levers, https://www.ebay.co.uk/itm/193319837569
edit - for some reason, people like to buy these tiny, not-terribly stable trailers, then bolt all sorts of stuff to them, making them as topheavy as possible. I don't get it personally.

I was after the name of the square section and the black brackets, is it off the shelf stuff? Many thanks
You've kind-of got the names already 
They're bits of some generic roofbar brackets that the trailer's owner has taken a drill to. That plus some stuff from the B&Q hardware aisle.
I hope I'm being disparaging enough I know that nobody likes to spend money, but there's reasons the factory brackets are doen the way they are. eg, not just tearing out the trailer sides if you hit a pothole.
If you must copy something, look closer at the factory setup and mimic that.

You could rig that up with basic tools out of box section steel/aluminium, bolting uprights to the side of the trailer then bolting horizontal bars to the uprights then the roof box to the horizontals if that makes sense.
Something like this would be very user friendly to work with.

A jigsaw with a metal blade, combi drill and HSS bits for drilling through the metal and some adequate nuts and bolts. That's if you aren't too bothered about how it looks.

Pretty sure roof box clamps designed for vehicles with roof rails/bars would simply clamp over the sides of the trailer.
Always assumed mine would, should I ever need to
Unlikely, they're usually quite a specific profile. Even cars within the same range/ manufacturer can have different profiles, let alone trying to clamp it to some random sized box section. Always assumed mine would, should I ever need to
