Hi OzBuzz; the only difference for the 8 frame hives is the width; 13 3/4"=350mm. I thought you guys use the same inches we do!
Oh i was waiting for the 'same unit of measure' comment
nah, we use special inches!
So is that 13 3/4 inches internal width? so it would be 13 3/4 plus the timber thickness for the external width
