We offer UK National sized Flow Supers to add to existing UK National beehives, on our European website.
A UK National is a type of beehive which is shorter, wider and deeper than a Langstroth 10-frame deep.
A Langstroth is only just shorter than a UK National, in fact, you can put a Flow Super Classic 7 Frame (equivalent in size to a 10 frame Langstroth beehive) on a UK National and it will just cover the outside ends of the UK National sized box. If you're willing to leave the ends like this then you can just add some straight pieces of wood or plywood to cover the gap between the narrower Flow Super Classic and the UK National. A triangular section of wood about 60mm (2.5") wide on each side of the Flow Super would do it.
If you are keen you can adapt a UK National super and shorten the Flow Frames as follows:
Begin by taking off the cables (on a table so that it doesn't completely disintegrate) and removing pairs of 'blades'. Each pair is 11.8mm (0.466"). You will have to measure how much shorter it needs to be and divide this by the above figure. You will need stainless steel tie-wire of around 1mm diameter to rebind the whole thing together. Remember to cross the wire (figure 8 shape) to support the base and top of the frame and twist it to tighten. 8 of these frames will fit in a UK National.
Please note, while we encourage the creative use of our product, disassembly or modification of your Flow Frames from their original format will void your warranty. To adapt a UK National you will have to view our Langstroth box modification videos and adapt that to the UK National design. A UK National is higher than a Lang deep. You will have to cut it back around three sides to bring it down to the correct height, a bit tricky.
