POSITION A
The A position is the first extension bar attachment
position. This position is used when the array is
suspended from two points (Front and Rear, or Side
to Side), and can be used for single-point hangs if
the prediction shows that a shackle can attach to a
physical attachment point on the extension bar.
POSITION B
The B position is used when the LAC prediction for
suspension from a single point indicates that the
desired array site angle cannot be achieved with a
shackle hole in the A position. Sliding to the B posi-
tion may better align the preferred shackle attach-
ment point in the LAC prediction with an available
physical position on the extension bar, ensuring that
a desired array site angle can be achieved.
POSITION C
The C position is used similarly to the B position,
offering the same ability to increase the number of
available physical positions for shackle attachment
when an array is suspended from a single point.
Sliding to the C position may better align the pre-
ferred shackle attachment point in the LAC predic-
tion with an available physical position on the exten-
sion bar, ensuring that a desired array site angle can
be achieved.
