To attach the double-stud swivel-ring fittings to
the enclosure rigging track, as shown in
the enclosure rigging track, as shown in
Figure 7
,
grasp the fitting between the thumb and first two
fingers. Push in the spring-loaded safety locking
pin with your free hand and lift the outer locking
ring over the pin by pressing with your thumb.
Continue to press with your thumb until the two
legs of the fitting are fully exposed. Insert the two
round feet on the end of the legs into the round
cutouts in the track and slide the fitting to the
desired position. Center the main body of the fit-
ting over one of the track cutouts, with the feet
located on either side (i.e., the feet positioned di-
rectly under the teeth of the track). Release the
outer locking ring. The round protrusion on the
bottom of the fitting should lock into the round cut-
out in the track, with the locking ring retracting to
its normal position, allowing the safety pin to reap-
pear and extend over the locking ring. If the fitting
does not lock into the track, nudge it along the
track and wiggle as necessary until it settles into
position. If the outer locking ring does not fully re-
tract, push the ring towards the track until the
safety pin reappears and extends over the locking
fingers. Push in the spring-loaded safety locking
pin with your free hand and lift the outer locking
ring over the pin by pressing with your thumb.

1.5 Grid Details
ATM Fly-Ware
TM
manufactures the MEGS-4000-T
grid, shown in
Figure 8
, specifically for the
X-Array™ loudspeaker systems. The grid is com-
pletely compatible with the X-Array™ systems,
and has track on the front and rear for connecting
to the top enclosure in an array column. The track
on the rear of the grid, shown in
pletely compatible with the X-Array™ systems,
and has track on the front and rear for connecting
to the top enclosure in an array column. The track
on the rear of the grid, shown in
Figure 8b
, has a
single large cutout for inserting the Xrhg grid
hinges, and has hinge locking-pin holes similar to
the track on the rear of the enclosures. Standard
double-stud aircraft fittings cannot be used at the
rear of the grid. The track on the front of the grid,
shown in
hinges, and has hinge locking-pin holes similar to
the track on the rear of the enclosures. Standard
double-stud aircraft fittings cannot be used at the
rear of the grid. The track on the front of the grid,
shown in
Figure 8c
, provides two attachment posi-
tions for the Xrsl or Xrss rigging straps. A grid

which sets the splay angle between adjacent col-
umns. Each grid comes with two long couplers in
the front and two short couplers in the rear. The
couplers on one side of the grid have male ends
while the couplers on the other side of the grid
have female ends. This allows several grids to be
linked together by inserting the male ends of one
grid’s couplers into the female ends of another
grid’s couplers, as shown in
umns. Each grid comes with two long couplers in
the front and two short couplers in the rear. The
couplers on one side of the grid have male ends
while the couplers on the other side of the grid
have female ends. This allows several grids to be
linked together by inserting the male ends of one
grid’s couplers into the female ends of another
grid’s couplers, as shown in
Figure 8f
. The cou-
plers are secured to the front and rear grid bars
with bolts or quick-release pins. The front and
rear couplers may be swapped from front to rear
to attain a wider range of splay angles. Two ex-
amples are shown in
with bolts or quick-release pins. The front and
rear couplers may be swapped from front to rear
to attain a wider range of splay angles. Two ex-
amples are shown in
Figures 8g
and

The working-load structural-strength ratings of the
X-Array™ loudspeaker systems allow a maximum
weight of 726 kg (1,600 lb) to be suspended in a
single column, which is well within the working-
load limit of the ATM Fly-Ware™ MEGS-4000-T
grid. When using the MEGS-4000-T grid, always
follow the manufacturers instructions, recommen-
dations and safety precautions, and never exceed
any structural limit as provided by ATM.
