Hi Alon, Those measurements on the KB are for the Spring I......we will be sure to make that notation now there is a Spring II
I have a 12 shaft Spring II and these are my measurements with the blocking pin in.
Floor to bottom edge of lower lamm 33 cm
Floor to bottom edge of upper lamm 52.5 cm
Floor to bottom edge of lower shaft bar 64 3/4 cm
Floor to bottom edge of upper shaft bar 100.5 cm
And just a note to watch the height of your beater....if you beater it too high then the shed won't be able to open fully :)
Hope this helps.
