Fridge gambrel rail.

Ah, but the back panel is quite different. You can always check the top of the fridge with something like a stud detector that can also check for electrical cables.

The unistrut looks like the way.....pretty cheap as well. Many thanks!

If you decide to go for it, I bought one of these, two of these, two of these, one of these (I squashed the ends in a vice so they'd fit in the unistrut holes) plus some short M10 bolts and some of these to fasten them into.
