Installing a number of panel radiators on my project, and unfortunately some of the grounds (within the timber stud walls) for the hanging brackets are in the wrong position.

It's my own fault as in a few instances I position the grounds for say a 1000mm wide rad, where a 1200 wide rad is being installed.

It can be overcome by opening the wall, installing more grounds and reboarding, reskiming but understandably I want to avoid that.

Not keen on radiator support feet either tbh.

Does anyone know if brackets with an extra wide wall plate are available as I think that my bridge the offset of ground to radiator hanging lug. Perhaps I could just buy some metal and bend some up myself.

Welcome any members ideas of how to overcome this issue?

Wide wall plate brackets do exist but they are not common on the shelf. What I have seen done is a short length of steel flat bar fixed through the board into the noggin, then the bracket mounted onto the bar to pick up the lug position. Just make sure it is solid, because a 1200 rad full of water pulls a lot of weight on those fixings.

Any idea where I might find these wide brackets? In some instances I may only be ~20mm or so off the stud, I'll have a search online.

The steel flat bar sounds like an idea.

Thinking about it perhaps a U section channel would work even better as the web could accomadate the head of the bolt connecting the bracket to the channel.

Also found these online which I think would work, although they will be visable:https://www.walraven.com/en/products/walraven-radiator-fixing-set/

How about using those Walraven fixings at the bottom, fixed securely into the stud - these will take the main load.

Then you can fix the original concealed radiator brackets into plasterboard with something heavy duty like grip it anchors - these will be less loaded, just stopping the radiator tilting or being pulled.

That way you avoid visible top brackets

I called Walraven and they don't actually stock those particular brackets, I spoke to a very helpful chap and by coincidence he needed the same bracket himself and randomly found a pair of them in the bargain bin in Toolstation, however I can't see them listed on their website.

I think I'll have to find some suitably wide angle metal and fabricate a wider bracket in the garage.

Sorry, I missed your follow up on where to find them. Honestly I do not have a reliable off the shelf source to point you to, they tend to turn up through specialist radiator fixing suppliers rather than the usual trade counters, and stock seems hit and miss. For only 20mm or so I would go with your fabrication idea. A short length of angle or channel fixed solidly into the stud, with the bracket bolted through it, will do the job and you can set the lug position exactly. Torre's point about taking the main load at the bottom is a good one too, so the top fixing is not doing all the work on its own.
