If, as in our example, D becomes less than 400 mm it is necessary to recalculate as below and cut one of the
full
length luff extrusions
according to Dnew and one of the full length distance tubes according to Enew. Note that
the original top luff extrusion and the original top distance tube will now be used as intermediate extrusions.
