General Hardware Information

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.

A licensed Professional Engineer must approve placement and method of attachment to structures
prior to installation of any overhead object. The following performance standards should be provided
to the Professional Engineer for design purposes: Uniform Building Code as applicable, Municipal
Building Code as applicable, Seismic Code as applicable. Installation of 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.
Hardware Inspection & Maintenance
Suspension systems are comprised of mechanical devices and, as such, they require regular
inspection and routine maintenance to insure proper function ability. JBL VP Series loudspeakers
must be inspected for fatigue at least annually. The inspection shall include a visual survey of all
corners and load bearing surfaces for signs of cracking, water damage, de-lamination, or any other
condition that may decrease the strength of the loudspeaker enclosure. Accessory hardware provided
with or for JBL VP Series loudspeakers must be inspected for fatigue at least annually. The inspection
shall include a visual material survey for signs of corrosion, bending or any other condition that may
decrease strength of the fastener. For other fittings used, refer to the manufacturer’s inspection and
maintenance guidelines for process.
