The MSL-4 equipped with the L-Track rigging system weighs
205 lbs (93 kg). The
maximum recommended load
for an
L-Track-equipped MSL-4
at vertical pull
using any 2 points
is 1500 lbs. (682 kg)
.We strongly recommed using all four
rigging points per end. This
working load
is based on a 5:1
safety factor
1
.
L-Track provides eight rigging points (four on the top and
bottom end of each cabinet); the maximum working load of
each individual point is dependent on the direction in which
the cabinet is being pulled at each particular point. Figure 1 on
the following page shows the working loads for each point as
they vary depending on cabinet pull angle.
!
NOTE: When flying the MSL-4 using the L-Track system,
it is absolutely imperative that you do not exceed either
the maximum recommended working load for an entire
cabinet or the working load of any individual rigging point.
All working load limit ratings assume the cabinet, fittings,
and L-Track are in new condition. If not, the load ratings can
be reduced significantly. It is important to inspect the rigging
hardware regularly and replace worn or damaged components
immediately.

Depending upon your geographic location a different safety factor may be required. All Meyer Sound products must
be used in accordance with local, state, federal, and industry regulations. It is the owner’s and/or user’s responsi-
bility to adhere to local regulations and evaluate the reliability of any rigging method for their application. Rigging
should be done only by experienced professionals.
