The arrangement in the following picture is
an unstable one. The smaller the splay angle between
cabinets, the more the stability. Obviously, the most
reliable stack in terms of stability is the one when the
splay angle between all of the cabinets is 0º.
As mentioned above, the hole in which the
safety pin is inserted in the PL-48S piece will
determine the splay angle of the bottom box, be it 0º or
-1.6º. The following pictures will make things more
clear.
The angle between the box and the platform
will be 0º when the safety pin is inserted in the hole
on the bottom of the back guide, and the hole on the
bottom of the PL-48S_2 piece.
The angle between the box and the platform
will be -1.6º when the safety pin is inserted in the hole
on the bottom of the back guide, and the hole on top of
the PL-48S_2 piece. Let us go now through the
complete process of stacking the boxes after they
have been previously flown.

After having rolled a PL-48S platform under
the array, the PL-48S_1 pieces (1,2 and 3) must be
detached from the platform and introduced (4) in the
front rigging structure of the lower box.
