Installation of the
Shoulder Eye Bolts
Rigging of the FRi-Series is done with readily available
3/8-16 forged shoulder eye bolts. To install the eye bolts,
follow these steps:
1.
Determine the intended location for the eyebolts on
the cabinet.
2.
Remove and replace the 3/8-16 Phillips head screws
ONE AT A TIME. Replace screws with eye bolt, using
a washer (supplied) under each one.
3.
Tighten each eye bolt “hand tight” and then torque
an additional

turn to accomplish
proper alignment.
WARNING: NEVER REMOVE MORE THAN ONE
3/8-16 PHILLIPS HEAD SCREW AT A TIME!
Removing two adjacent screws may cause the heavy
steel bracket to fall into the box, requiring disassembly of
the enclosure to put it back in place.
The FRi Series features internal heavy gauge steel
reinforcing brackets that are not only designed to provide
high safety factor support for the 3/8-16 forged eyebolt
rigging, but also to unitize the internal panels for each
enclosure. These corner braces are required to maintain
the structural integrity of the cabinet to performance levels
listed in this manual.
Basic Principles for Suspending
FRi Loudspeakers
Many “suspendible” loudspeaker designs offer “t-nut” style
mounting without using top and side enclosure panel
braces, thus producing lower safety factors. Therefore,
each FRi full range loudspeaker enclosure is furnished
with 12 fully supported mounting points to provide maximum
vertical or horizontal suspension. All systems have been
structurally certified to a minimum of 8 to 1 safety factor
loading. Each input panel provides safety information and
maximum safe multi-cabinet rigging data. Maximum safe
rigging configurations should never be exceeded.
