This pic is a little bad, but I tried to show the difference in clearance between 'normal' fittings and the BP's. What you really can't see is the metal plate
will not fit with the BP's screwed all the way in. And if you put two of them together, forget. Very similiar to the FuZion issue. .

Shame, I had high hopes for these. Amazing fittings, but you have to choose your blocks very carefully.
