The transition between the portion with full cross-section and the portion inside thereof consists of a recess, in which the portion with full cross-section fits and of a plane surface, which in principle is one quarter of the cross-sectional area for the full cross-section and extending perpendicularly to the longitudinal direction of the unit.
