A note on eyebolts
Eyebolt working load limits are
significantly de-rated when angular lifts
are applied. If an application requires
an angular lift greater than 45˚, a swivel
hoist ring or similar fitting must be used.
These fittings have full swivel and pivot
action which helps avoid side loads.
WARNING: When the FB100 Flybar is used
to suspend a system, it cannot retain
a 10:1 design factor at certain pick points.
In some situations, suspended and installed arrays may
be configured with other design factors (e.g. 8:1 or 5:1),
LOUD Audio, LLC. only recommends using the desired
10:1 design factor.
