Installation Guide
Swivel Beam Clamp
The MultiMount-3RDX-120 provides a wide range of speaker aiming positions
and adapts to standard off-the-shelf schedule 1.5” NPT and NPS threaded
steel pipe. The speaker mount employs two standard mounting hole patterns,
the 3.44” x 6.88” and the 2-3/4” x 5”.
Step 1:
A 1.5 NPT or NPS pipe should already been installed from
the ceiling before proceeding to attach the MM-3RDX-120
(Figure 1).
Step 2:
Attach MM-3RDX-120 to 1.5 NPT or NPS pipe, then lock
with set screw
(Figure 1)
.
Step 3:
Secure speaker to the speaker adapter plate. Pull a sufficient
length of signal wire and safety cable to reach the speaker’s terminal block
and safety cable anchor point. Align the speaker’s four mounting points
with the mount’s matching hole pattern. Use the speaker manufacturer’s
recommended fasteners; tighten fasteners permanently through the mount
and into the speaker cabinet
(Figure 2)
.
Note to installers
Due to the wide variety of wall structures, materials and mounting
methods, these instructions assume that the installing contractor will
exercise proper judgment in selecting the mounting area and hardware.
As a guide, the installation, when complete should be capable of
supporting 5 to 10 times the actual applied load. Also, always use a back
up safety system such as a safety cable.
To assure a trouble free installation, read through and follow these
instructions carefully before beginning. If you have doubts about
the integrity of the structure you are mounting to or you are not
sure about the proper hardware to use, consult a structural and/or
hardware specialist.
