1.2 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 product traceability controls. Compliant hardware will be refer-
enced with a working load limit (WLL) and a traceability code.
1.3 IMPORTANT SAFETY WARNING
The information in this section has been assembled from recognized engineering data and is intended for informational
purposes only. None of the information in this section should be used without first obtaining competent advice with re-
spect to applicability to a given circumstance. None of the information presented herein is intended as a representation
or warranty on the part of JBL. Anyone making use of this information assumes all liability arising from such use.
All information presented herein is based upon materials and practices common to North America and may not directly
apply to other countries because of differing material dimensions, specifications, and/or local regulations. Users in oth-
er countries should consult with appropriate engineering and regulatory authorities for specific guidelines.
Correct use of all included hardware is required for secure system suspension. Careful calculations should always be
performed to ensure that all components are used within their working load limits before the array is suspended. Never
exceed the maximum recommended load ratings.
Before suspending any speaker system always inspect all components (enclosure, rigging frames, pins, eyebolts, track
fittings, etc.) for cracks, deformations, corrosion, or missing/loose/damaged parts that could reduce strength and
safety of the array. Do not suspend the speaker until the proper corrective action has been taken. Use only load-rated
hardware when suspending JBL suspendable loudspeaker models.
1.4 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 Engi-
neer for design purposes: Uniform Building Code as applicable, Municipal Building Code as applicable, and Seismic Code
as applicable. 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.
