There are not really any single commercial cages that are big enough for boars and that meet the recommended measurements but there are options…..
The largest commercial cage available is the ferplast plaza 160, even that still comes in 20cm smaller than the recommended 180x60cm (which is fine for some pairs but for others it can be tight). I am sure you can buy 40cm extension pieces for it though so you could make it 200x60cm if the extension pieces are available to you.
The other option option is to get two commercial cages and join them together. You could buy two standard 120cm cages (which on their own are too small) and connect them.
I had a ferplast plaza 160 as one of my spare cages for when my piggies had to come inside. It was absolutely fine for one of my boar pairs. However it would have not worked for my younger boar pair, it would have been a bit too small for them (they had twice as much space and even that wasn’t enough for them - their bond has since broken anyway and the ferplast plaza now houses a single boar as his winter home).
(This is why a lot of indoor boar owners do go for 5x2 c&c cage because they definitely are big enough, and they can have lids fitted to them but they aren’t always an option for everyone)
