order to avoid any conditions that may be dangerous for
persons or structures.

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qualiedprofessional,suchasa
licensed Professional Engineer, review and approve the
design before its implementation.
3.Installation:Haveaquali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
U-brackets,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 configurations 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-certified rigging
system for supporting the loudspeaker from structure.
Rigging Notes
TheHD1221’sintergralmountingpointsaredesigned
to support only the weight of their own loudspeaker
with suitable, external hardware. This means that each
HD loudspeaker must be supported independently of
any other HD loudspeaker and any other loads.
A minimum of two rigging points must be used to hang
an HD1221. More may be used for creating the desired
hanging angle as shown in the illustrations on the
following page. All mounting points are fully load
bearing so any two may be used for rigging; no mounting
points are restricted to angle control only.
12 Fly Points
