Working Load Limit
The JBL SoundFactor Install loudspeakers are supplied with built-in internal braces to be used with the
supplied forged shoulder eyebolts or other approved fastener.The system is designed to facilitate the sus-
pension of the loudspeaker by a qualified person familiar with rigging hardware and industry practices.
IMPORTANT! You must ensure that ALL installation procedures specified in this manual
are carefully followed. Improper installation may result in damage, injury or death.
The working load limit (WLL) of any JBL SoundFactor Install loudspeaker is maintained as long as no
more than one loudspeaker is suspended by a minimum of two primary suspension points with no addi-
tional load placed on the loudspeaker enclosure. The JBL SoundFactor Install loudspeakers are intend-
ed for SINGLE-BOX SUSPENSION ONLY. DO NOT HANG A SECOND SPEAKER FROM A SOUND-
FACTOR INSTALL SPEAKER.

General Hardware Information
Any hardware used in an overhead suspension application must be load rated for the intended use.
Generally, this type of hardware is available from rigging supply houses; industrial supply catalogs and
specialized rigging distributors. Local hardware stores do not usually stock these products. Hardware that
is intended for overhead suspension will comply with ASME B30.20 and will be manufactured under prod-
uct traceability controls. Compliant hardware will be referenced with a working load limit (WLL) and a
traceability code.
All SoundFactor Install loudspeakers include a rigging hardware kit (part# 229-00009-01) which includes
3 forged shoulder eyebolts and 3 washers. When installing these speakers, use hardware found in the kit
provided. For additional rigging components, consult with a professional rigging hardware supplier.
Sources for specialized rigging hardware may be found on page 11.
Proper Use of Forged Shoulder Eyebolt
The JBL SoundFactor Install loudspeakers are supplied with three forged M10-1.5 x 35 mm shoulder eye-
bolts with appropriate ratings and certified standards compliance, for use in overhead suspension appli-
cations. To install the eyebolts into the provided threaded holes on the loudspeaker, first remove the fac-
tory installed, flat head machine screw using a 6 mm hex key wrench. The M10-1.5 threaded internal
brace is accessible once the flat head machine screw is removed. Deposit thread lock adhesive, follow-
ing the adhesive manufacturer's instructions, onto the threaded tip of the eyebolt. Install the forged shoul-
der eyebolt as a replacement for the machine screw, being careful not to cross-thread the fasteners.There
should be little resistance when installing any fastener. As a general rule for "soft surface" installations
such as a wooden surface, the suggested torque is achieved by installing the fastener until snug and then
rotating the fastener an additional 180 degrees (1/2 turn).
The load imposed on the eye of the eyebolt fastener must remain in the plane of the eye only. When any-
thing other than a straight-line pull is used, the provided forged, shoulder eyebolt load rating must be
adjusted as follows:
Direction of Pull
Adjusted Working Load
45 degrees
25% of rated working load
In-Line
45º

Proper Sling Termination
The slings described herein are "suspension slings" and are different from "lifting slings" as defined by
government regulatory bodies. Do NOT use hardware chain. The JBL SoundFactor Install loudspeakers
must be used in static suspension applications only. Wire rope suspension slings are suggested for all
installations requiring suspension of the JBL SoundFactor Install loudspeakers. The suggested wire rope
is identified as 1/8" 7 x 19 Galvanized Aircraft Cable (1/8- 7 x 19 GAC). The minimum working load limit
(WLL) of this type of wire rope is 400 lb / 181 kg when terminated properly. If sling lengths are pre-deter-
mined and the wire rope slings are fabricated at a rigging supplier, the suggested termination is identified
as "swaged Flemish eye terminations with heavy thimbles and certification tags." If sling lengths cannot
be predetermined and slings must be fabricated on site, the suggested termination is identified as either
a load rated "compression sleeve" or a forged "wire rope clip". Compression sleeves, such as the
Nicopress devices, require a specialized compression tool and associated check gauge. Wire rope clips
require an end-wrench, socket wrench, and/or adjustable wrench (spanner). The following table defines
the load rating adjustments associated with each termination type if the terminations are made accord-
ing to manufacturer's instructions:

Rigging Connections
Some installations require the use of a removable connection between the structure and the loudspeak-
er. Hardware commonly used for these applications includes:
Quick Link
Screw Pin Anchor Shackle
Used in-line or at an angle up to
45 degrees and can combine two
wire ropes into one. A mouse wire
(aka safety wire) must be used
after installation.
Used in-line with only one wire
rope per end. Only use load rated
quick links, which will have the
WLL imprinted on the component.
Some installations require the adjustment of the length of one or more slings. Common hardware used
for these applications include:
Turnbuckle
Used in-line with only one wire rope per end
and can be adjusted to length. A mouse wire
must be used after adjustment is complete.
Note: Use only turnbuckles with closed,
forged eyes.

Attachment to Structures
A licensed Professional Engineer must approve the placement and method of attachment to the
structure prior to the installation of any overhead object. The following performance standards
should be provided to the Professional Engineer for design purposes; Uniform Building Code as applica-
ble, Municipal Building Code as applicable, Seismic Code as applicable, and a minimum of a 5:1 design
factor throughout the suspension system.
The installation of the hardware and method of attachment must be carried out in the manner specified
by the Professional Engineer. Improper installation may result in damage, injury or death.
The following renderings represent some of the common methods of attaching to a structure. These ren-
derings are intended as a reference only, and are not appropriate for many installation circumstances. In

Inspection, Maintenance and Liability
Suspension systems are comprised of mechanical devices and, as such, they require regular inspection and routine main-
tenance to ensure that safety has not been compromised. The JBL SoundFactor Install loudspeakers and associated sus-
pension components must be inspected for fatigue at least annually and immediately following exposure to impact,
mechanical shock, fire, water or other hazard. The inspection must include a visual survey of all corners and load bearing
surfaces for signs of cracking, water damage, de-lamination, and any other condition that may decrease the strength of
the loudspeaker enclosure or associated suspension components. The forged shoulder eyebolts provided with the JBL
SoundFactor Install loudspeakers must be inspected for fatigue at least annually. The inspection must include a visual sur-
vey of the material for signs of corrosion, bending or any other condition that may decrease the strength of the fastener.
Additionally, the eyebolts must be checked for possible spin-out of the enclosure. For all other hardware and fittings, refer
to the hardware manufacturer's inspection and maintenance guidelines for process. Should any signs of unsafe conditions
be observed, repair or replacement of the deteriorated component(s) must be completed before anyone other than some-
one performing the repair is allowed access to the vicinity of the unsafe condition.
Note:
The working load limit (WLL) of the JBL SoundFactor Install loudspeakers includes; a design factor equivalent to or
exceeding ASME B30.20, VBG70, VBG9a and the manufacturer's proprietary performance standard.
All implied warranties, including warranties of merchantability and fitness for particular purpose, are limited in duration to
the length of the warranty. JBL's liability shall in no event exceed the cost of any defective product and shall not include
incidental or consequential damages of any kind, even if JBL has been advised of the possibility. Some states do not allow
limitations on how long certain warranties last and/or do not allow exclusion of incidental or consequential damages, so
the above limitations and exclusions may not apply to you. This warranty gives you specific legal rights, and you may also
have other rights which vary from state to state.
JBL is not responsible for the application of its products for any purpose or the misuse of this information for any purpose.
