A really easy to fit and robust shelf, ideal for the purpose. I bought another one for a different radiator in the house without realising the space at the back and the presence of a shallow windowsill above it makes it impossible to fit as it is. However, we're pretty sure that with a bit of a tweak to the shape or length of the struts is all that's needed to be able to use that one too. I mention this to warn others to be really careful about checking measurements and the shape of the supports but overall, a very good value shelf for the purpose.
