Location of Pick Points
There are fifteen (15) load-rated pick points on MD-LP enclosures; four
each on the top and on the bottom, two each on the sides, and three on
the rear of the enclosure.
There are sixteen (16) load-rated pick points on MD-SP enclosures; four
each on the top and on the bottom, and four each on the sides.
These pick points are indicated with arrowheads on the illustrations.
Note the pick points on the cabinet bottom or sides are not shown, but
are identical to those indicated on the cabinet top (MD-LP) or the side
shown (MD-SP).
As shipped from the factory, each pick point has a strength-rated flat
head bolt installed. These bolts are load bearing components of the
enclosure. Do not remove these bolts except to replace a bolt with a
forged-shoulder eye bolt. If a flat head screw is lost, contact QSC's Tech-
nical Services department for a replacement.
Ensure all pick-point fasteners are installed and tightened to 40
in-lb (4.519 N-m) to maintain enclosure's rated strength. Air leaks
resulting from missing hardware will degrade the loudspeaker's
performance.
Use only 3/8-inch, 16 threads per inch forged shoulder eye bolts,
QSC part number SR-000096-00. Contact QSC Technical Services
department for complete information.
Before placing, installing, rigging, or suspending any speaker
product, inspect all hardware, suspension, cabinets, transducers,
brackets and associated equipment for damage. Any missing, cor-
roded, deformed, or non-load rated component could significantly
reduce the strength of the installation, placement or array. Any
such condition severely reduces the safety of the installation and
should be immediately corrected. Use only hardware which is
rated for the loading conditions of the installation and any possi-
ble short-term, unexpected overloading. Never exceed the rating
of the hardware or equipment.
Consult a licensed, Professional Engineer regarding physical
equipment installation. Adhere to all regulations regarding the
safety and operation of flying equipment.
