Aircraft Pan Fittings Only
The MSL-4 without L-Track weighs 184 lb (83.5 kg). The
maximum recommended load for an MSL-4 with aircraft pan
fittings is 600 lb (273 kg). This working load is based on a 5:
1 safety factor. The MSL-4 has six rigging brackets (three on
top and bottom of the cabinet); each bracket is capable of sup-
porting the full working load of the cabinet.

Rigging load ratings assume a straight tensile pull and that the
cabinet is in new condition with aircraft pan fittings. If these
conditions are not met, the load ratings can be reduced sig-
nificantly. Load ratings can also be reduced by age, wear, and
damage. It is important to inspect the rigging hardware regularly
and replace worn or damaged components immediately.

The cabinet, exposed electronic circuitry, and drivers can receive
protective treatment that permits safe use in wet conditions.
