2. The use of safety points in rigged or ‘flown’ systems is highly recommended. The
Vertical Fly Kit includes eyebolts intended for this purpose. The eyebolts should ideally
be attached to unused rigging fittings on the tops of the enclosures and connected to
safety cables. Safety cables are a second set of ‘backup’ cables that can sustain the
load in the event that the primary suspension system fails. Safety cables must always
be installed with little to no slack. A slack safety cable will result in a serious shock
load to the cable and the rigging hardware if the primary rigging fails. Such a shock
load could cause the safety cable or other rigging components to fail as well.
3. After the primary rigging and the secondary safety cables have been attached, the
loudspeaker array is now ready to be raised to its proper trim height.
4. Two threaded rigging fittings are provided on the rear of each enclosure. These fittings
are intended to be used as pull-back points, if a steep angle of downward inclination is
required. They are not intended to be used as the primary rigging points to suspend the
enclosures.
WARNING: Never reeve a primary support cable or a safety cable through a pair of
eyebolts or shackles (see drawing below). When a cable or sling is reeved through a pair of
eyebolts, it will load the eyebolts both laterally and vertically with a vector force that
greatly exceeds the actual weight of the loudspeaker array. The proper solution is to
provide separate cables for each one of the eyebolts.
