Install Rigging Plates (angled edge forward) into the
slots on each end of the Flybar. Align each Plate’s
top front and 3rd-from-the-top rear holes with the
holes in the Flybar as shown. Fully insert two Safety
Pins per Rigging Plate. Position both Rigging Plates
an equal distance from the front of the Flybar. The
tilt angle of the array can be adjusted by positioning
the first Module forward or back on the Flybar.
To insert a Safety Pin into a hole, depress its rear
plunger so that the two Ball Stops will recess into
the pin body. Once it is fully inserted into the
Module’s End Bracket release the rear plunger, and
the ball stops will lock the Safety Pin into place. A
fully inserted Safety Pins will pass through the
Flybar/End Bracket’s outer rail, the Rigging Plate and
the Flybar/End Bracket’s inner rail.
LOAD RATING
Safe working load is 4000 lb./Module.
Calculated at 5:1 safety factor + pull tested.
Maximum column length is 10 Modules.

Lower the Flybar and align the Rigging Plates
so they fit into the Module’s Top End Brackets.
As they engage, you will see the spring-loaded
Rotating Cams snap onto the Rigging Plates’
V-Grooves. Once both sides are engaged, rest
the entire weight of the Flybar onto the
Module. Each Top End Bracket has two holes
with a yellow ring around them. Fully insert the
Safety Pins into these holes, 2 per side, 4 in all.

Roll the first Module on its Caster
Pallet beneath the Flybar so the
top of the Module faces front. (The
end of each Module has a notch
that faces the Module’s top
surface)

Remove the Cart’s Flyclip from the back
of the Module.

Raise the Flybar and Module a few
inches so when you disconnect the
Caster Pallet it will drop an inch or so
onto the Cart.
9
Two latches, one on each end Module,
hold the Caster Pallet in place. Insert
the Allen Wrench into the latch hole
and turn counterclockwise, freeing the
Pallet. Remove the loose Pallet and
wheel away the Cart.

Raise the Array so the Module’s Bottom End Bracket is chest high. At this time, select the angle at which the next
Module is to be hung. The faces of any two adjacent Modules can be arrayed at 0°, 5°, 10°, 15°, 20°or 25°. Each
Rigging Plate offers eight holes (4 sets of two). Each Module’s Bottom End Bracket offers six holes (three sets of
two). Angles are determined by aligning the proper Rigging Plate holes with the proper Bottom End Bracket holes
(see diagrams). Install Rigging Plates into both ends of the Module.

This manual details general rigging practices appropriate to
the sound industry, as they would apply to the rigging EAW
KF860 Series loudspeaker systems. It is intended to familiar-
ize the reader with rigging hardware and techniques for sus-
pending EAW KF860 Series loudspeaker systems overhead.
Only persons with the knowledge of proper hardware and
safe rigging techniques should attempt to suspend any sound
systems overhead. Prior to suspending any EAW KF860 Series
loudspeaker systems overhead, it is essential that the user
be familiar with the strength ratings, rigging techniques and
special safety considerations appropriate to suspending loud-
speaker arrays overhead. The rigging techniques and prac-
tices recommended in this manual are, of necessity, stated
in general terms to accommodate the many variations in
loudspeaker arrays and rigging configurations. As such, the
user is expressly responsible for the safety of all specific
EAW KF860 Series loudspeaker array designs and rigging con-
figurations and to ensure that all local safety regulations are
followed.
Securement strength requirements should take into consid-
eration any dynamic loading and other contributing factors
affecting the flown system. It is the responsibility of the
user to determine the proper safety factor in specific appli-
cations and the required strength rating of the connection
points. EAW strongly recommends that the EAW KF860 Series
loudspeaker systems be used in accordance with all federal,
state and local regulations, and strongly urges the user to
review and comply with all federal, state and local regula-
tions relative to proper securement of flying or hanging loads
prior to usage.
Some aspects of rigging and other related fields for which
EAW manufactures, sell or distributes equipment are poten-
tially hazardous. Any person using this equipment is person-
ally responsible for their own safety. EAW transactions are
made with the assumption that the purchaser is a qualified
individual or will have only qualified individuals perform work
with the equipment. EAW will not be liable for any damages
arising from the use of equipment sold to purchaser.
