Rigging
HDAs may only be fl own horizontally. Use
M10 x 1.5 x 37 mm forged shoulder eyebolts or the
optional FB121 Flybar.
WARNING: The cab i net is suit able for rig ging
via its fl y points or the integrated fl yware only.
NEVER at tempt to sus pend the HDA by its
han dles.
Rigging Design Practices
Rigging a loudspeaker requires determining:
1. The rigging methods and hardware that meet static,
shock, dynamic, and any other load requirements for
supporting the loudspeaker from structure.
2. The design factor for and the required WLL
(Working Load Limit) for this support.
Mackie strongly recommends the following rigging
practices:
1. Documentation: Thoroughly document the design
with detailed drawings and parts lists.
2. Analysis: Have a qualifi ed professional, such as a
licensed Professional Engineer, review and approve the
design before its implementation.
3. Installation: Have a qualifi ed professional rigger do
the installation and inspection.
4. Safety: Use adequate safety precautions and
back-up systems.
Rigging Hardware and Accessories
Rigging Mackie loudspeakers will invariably require
hardware not supplied by Mackie. Various types of
load-rated hardware are available from a variety of
third-party sources. There are a number of such
companies specializing in manufacturing hardware for,
designing, and installing rigging systems. Each one of
these tasks is a discipline in its own right. Because of
the hazardous nature of rigging work and the potential
liability, engage companies that specialize in these
disciplines to do the work required.
Mackie does offer certain accessory rigging items,
primarily for attachment to the hardware integral with
the loudspeaker. Some items, such as eyebolts and
fl ybars, may be used with a variety of products. While
these accessories are intended to facilitate installation,
the wide variety of possible installation conditions and
array confi gurations do not permit Mackie to determine
their suitability or load rating for any particular
application.
Mackie is not in the business of providing complete
rigging systems, either as designers, manufacturers, or
installers. It is the responsibility of the installer to
provide a properly engineered, load-certifi ed rigging
system for supporting the loudspeaker from structure.
A note on eyebolts
Eyebolt working load limits are
signifi cantly de-rated when angular lifts
are applied. If an application requires an
angular lift greater than 45˚, a swivel hoist
ring or similar fi tting must be used – see
Figure A, for example. These fi ttings have
full swivel and pivot action which helps
avoid side loads.

IMPORTANT INSTALLATION WARNING
Installation should only be done by experienced, licensed professionals. Improper installation may result in damage
to the equipment, injury or death. As described throughout this manual, make sure the loudspeakers are installed
in a stable and secure way in order to avoid any conditions that may be dangerous for persons or structures.
