This unit is rather large and heavy, but it was never intended to be
used as a normal bee hive ad is in fact permenantly bolted down to a heavy duty
tressle.
37 mm was chosen for the frame pitch on this unit as such a wide
spacing allows for drone frames and other special frames to be accomodated. The
precise spacing of each individual frame is governed by the width of the
Hoffmann 'wings' of each frame as the frames are pushed together and any excess
space is taken up by a division board of suitable thickness for the gap
concerned.
