National brood frames, not a bother. The extractor is built for whatever they use on the continent so national supers don’t fit but this is easily sorted with a couple of cable ties (thanks to whoever mentioned that in an earlier post, worked a treat). Spun out 11 foundationless super frames, easy as you like, decanted into a 30l bucket through a double strainer which fits perfectly underneath. Easy to put together and clean afterwards. For the additional cost of a few cable ties and given it’s price point, I would be more than happy to recommend. Another 3 supers to extract this weekend!
