MultMount-3RDX-18 provides a wide range of speaker aiming positions and
adapts to standard off -the-shelf schedule 40 ½" NPT threaded steel pipe. This
allows the speaker to be positioned as close or as far away from the ceiling as
desired. The speaker mount employs two standard mounting hole patterns,
the 2" x 4-1/4" and the 2-3/4" x 5". The ceiling mounting plate adapts to most
overhead structures, including ceiling trusses, beams, Unistrut and other
structural components.
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. 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.
Be sure that all of the following items are included in this kit before proceeding:
1 pc Speaker Adapter Assembly
Note: Screws and washers to attach speaker to adapter plate are not included
Step 1: A ½ NPT pipe should already been installed from the ceiling before
proceeding to attach the MM-3RDX-18 (Figure 1).
Step 2: Attach MM-3RDX-18 to 1/2 NPT pipe, then lock with set screw
(Figure 1).

Step 3: Secure speaker to the speaker adapter plate

Pull a suffi cient 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).
