this came up a few pages back, so I contacted TEKNO direct and was told by thomas that the pics in the first page and the eb48 manual are incorrect, with the 1.5 hanger I was told to refer to the NB48 manual it is correct and the eb48 manual and set up sheets will be corrected in future printings, here is a snap shot of it. and it shows the center dot being 3.5 deg.
