What's the best strategy to install a designer rad (although this is applicable to all radiator types) ? By that I mean getting the brackets installed correctly so that the rad sits on all 4 brackets instead of the top two or bottom two, whilst also ensuring the pipes line up and fit into their respective fittings. Share your game plan. I installed a vertical rad yesterday and it was only sitting on the top two brackets and was a bit too low for the pipes - very annoying.
