INSTALLATION INSTRUCTIONS
Chief Manufacturing, a division of Milestone AV Technologies
Large Flat Panel Dual Arm Wall Mount
Model PNR™
The PNR is wall-mounted, rugged, versatile, and
installer-friendly. The PNR is compatible with the
standard (14” x 14”) PSB interface bracket in which a
display can be mounted in either the landscape or
portrait position on the PNR.
The dual arms on the PNR:
Extend from the wall 25” in length
Pivot up to 90º left or right of center
The standard PNR is shipped with the support posts for
the dual arms centered in the mount. The support posts
can be moved laterally right or left of center to readily
accommodate sites with limited wall space. The mount
also has over an i nch of height adjustment. The til t ra nge
for the display is 5º up and 15º down.
The PNR was designed f or fast i nstallati on. After dr awing
the plumb line and installing the two top l ag bo lts i nt o the
dual wall studs, the installer hangs the PNR on its top
bracket and installs two lag bolts in the bottom bracket.
Next, the installer makes the height adjustment, mounts
the display, and connects the power/audio/video cables,
which are diverted into the built-in path in the swing-out
arms. After making the lateral, rotational, and tilt
adjustments, the installation process is complete.
BEFORE YOU BEGIN
CAUTION: To prevent damage to the PNR, which could affect or void the Factory warranty, and to the equipment that
will be attached to it, thoroughly study all instructions and illustrations before you begin the installation. Pay particular
attention to the “Important Warnings and Cautions” on Page 2.
• The combined weight of the components installed on the PNR must not exceed 200 lbs. (90.72kg).
• The PNR wall mount must be installed on dual wall studs or supporting framework. The wall to which the PNR is
anchored must be capable of supporting five times the total weight of the mount and all attached equipm ent.
• If you have any questions about this installation, contact Chief Manufacturing at 1-800-582-6480.

INSTAL LATION
WARNING: Improper installation can result in serious
personal injury!
WARNING: It is the responsibility of the installer to
verify that the wall to which the PNR is anchored will
safely support five times the combined load of all
attached components and equipment. If not, reinforce
the structure before installing the PNR.
1. Locate two wood studs 16” apart on center
2. Determine the exact mounting location prior to
installation, considering screen size and the unit’s
total swing arm radius. Keep in mind that the PNR
must be mounted to wood studs that are 16” apart on
center.
NOTE: Mount the PNR between parallel wall studs or
other supporting framework that is vertical or
horizontal.
3. Using a stud sensor, locate the two wood studs where
you will mount the PNR.
4. Draw a level plumb line to indicate the desired height
of the top mounting bracket.
5. With an assistant, lift and hold the PNR against wall.
Use a pencil, awl, or small nail to mark the mounting
holes where two pilot holes will be drilled into the
center of the wood studs. Make sure the mounting
holes are level.
6. With an assistant, lay the PNR down on the floor.
7. Drill two pilot holes using a 9/32” dr ill bit where the
mounting holes were marked for anchoring the top
bracket. See Figure 1.
8. Install two 3/8” x 2-1/2” lag bolts (50) and two 3/8” flat
washers (60), through PNR Top Bracket and into
upper pilot holes.
NOTE: Do not tighten the lag bolts down at this time.
Leave enough space between the wall and lag
bolts to hang the PNR.

NOTE: Make sure washers are installed in front of the
top bracket, not behind the bracket.
2. Slide the PNR into the desired position on the wall
and tighten the two lag bolts.
Mounting the bottom bracket
1. Mark the two mounting holes in the bottom mounting
bracket (See figure 3). Make sure to align the holes
parallel to the holes drilled in the top bracket.
2. Drill two pilot holes in the wall studs using a 9/32” drill
bit.
3. Install two 3/8” x 2-1/2” lag bolts (50) and two 3/8”
washers (60) through PNR Bot tom Bracket into the
lower pilot holes.
4. Tighten all lag bolts.

CABLE MANAGEMENT
WARNING: Make sure your cables do not run through
a pinch point.
1. Route power/audio/video cables through the cable
channel in top arm (see Figure 8), allowing su fficient
slack in cables for extension and avoiding pinch
points, and secure cables using two clips and two
tiewraps (50, not shown).
2. Route power/audio/video cables along bottom arm
(see Figure 9), using tiewraps (50, not shown) to
secure cables to each arm, and through cable
channel.
CAUTION: To prevent equipment damage, do not
route cables through holes in the display mounting
plate.
3. Route power/audio/video cables to an open area

Swing Arm Adjustments
The dual swing arms are shipped installed in the center
of the top and bottom mounting brackets, which is the
standard mounting configuration.
The top and bottom mounting brackets have slotted
holes, allowing for lateral adjustment of the dual swing
arms.
After the top and bottom mounting brackets have been
installed between two wood studs 16” on center, the
swing arms can be adjusted or moved off center,
depending on the location of the mount, the size of the
display, and the lateral movement needed to rotate the
display.
The swing arms can be adjusted, as follows:
• Adjusting the Swing Arms Off-Center
With no disassembly required, you can adjust the swing
arms up to 1-inch to the left of center or up to 1-inch to
the right of center.
• Reconfiguring the Swing Arms Left of Center
With some disassembly and reassembly required, you
can move the swing arms to the left of center by
Top Bolts

Reconfiguring the Swing Arms to the Left or
Right of Center
To change of the dual swing arm mount configuration:
1. Remove the display from the mount.
2. Remove four bolts (two on the top and two on the
bottom) securing the swing arm assembly to the top
and bottom mounting brackets (See figure 14).
WARNING: The next step will release the arm
assembly from the mount. The arms and plate may fall
if you are not careful.
3. Move the swing arm assembly to desired location.

NOTE: The display may need to be repositioned in order
to gain access to the tension adjustment
screw(s).
3. Using the wrench provided with the mount, turn
adjustment bar clockwise to increase swing arm
tension or counterclockwise to reduce swing arm
tension. (See figure 17) and (See figure 18)
NOTE: Small adjustments of 1/8 turn or less are typically
all that is required to achieve desired tension.
4. Check swing arm tension. If desired tension is
present, tension adjustment is complete. If additional
tension adjustment is required, repeat steps 2 and 3
until desired tension is achieved.
NOTE: If changing from a smaller display to a larger
display it may be necessary to in crease swing
arm tension.
