Electrolux(?) do them. Have a look under boat suppliers. They're better than the Devon originals, as they clamp the roof board in place.
Try these guys; http://poptop-parts.co.uk/devon-bw75.htm These are practically identical to the original ones and you'd have to be a real nerd to spot the difference, which I did, and hence am.
They're the ones! Might be cheaper from a boat place (also used as boat vents). You do need to jigsaw the roof hole out by a couple of cm, but it's no great hassle. Much better than the original Devon carp.
£39 each FFS!! Same as original but not cos you've got to make the hole bigger? Or £8.95 on eBay for something that looks the same and you can't really see anyway, the choice is yours
Isn't that how Devon made their stuff in the first place? I'm sure you could find them cheaper from a boat shop somewhere, God knows why Electrolux made them.
thats a bit more like it £8.75 just need to check the size http://www.ebay.co.uk/itm/Caravan-R...252756?hash=item4afa707094:g:z9YAAOSwh-1W2tTZ
