11.5.3 Using Only Two Mounting/Rigging Points
If only the two rear mounting/rigging points are used, the loudspeaker will hang with a down-angle of
approximately 30 degrees. This may be ideal for many situations. If less down-angle is needed, four
mounting/rigging points should be used with the front mounting/rigging points used to pull up the
front of the enclosure to the desired down-angle. Alternately you can use the front two
mounting/rigging points and use a pull-back to set the desired down-angle. (Refer to “Pull-back
Capability”.)
When using two mounting/rigging points, be sure the rated loads for the mounting rigging points are
not exceeded. Refer to SECTION 11.5.4 for de-rating the mounting/rigging points when using them at
an angle.
11.5.4 De-Rating the Mounting/Rigging Points
Using the mounting/rigging points at an angle will de-rate the WLL for each point according to the
following formula:
WLL = Cosine (Angle) x 300. The Angle is in degrees from vertical pull.
NOTE: This formula is only valid for pull angles up to 75 degrees. From 75 degrees to 90
degrees the WLL remains as 75 lb. (34 kg).
11.5.5 Pull-Back Capability
To position the loudspeaker at the proper down-angle required for proper coverage, a pull or tie-back
is usually needed. A pull-back can be accomplished using the two bottom rear mounting/rigging
points for attachment of pull-back rigging.
The rear panel of the SLS enclosures is held in place by 3/8”-16 machine screws. On the SBS
enclosures, except for the SBS45, a dedicated 3/8”-16 pull-back point is provided. Instead of using
the two bottom mounting/rigging points as the pull-back points, a rear panel screw can be removed
and replaced by a rated eyebolt or other rated rigging hardware. This point can then be used as a
pull-back point to provide the correct down-angle needed. Use only hardware that is rated for the
intended use and load. The WLL for the rear panel mounting point is 60 lb. (27.2 kg) for any direction
of pull from 0 through 90 degrees.
WARNING:
Never exceed the working load limits (WLL) specified in FIGURE 11.
