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 24-7/8” 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 two inches of height adjustment. The tilt range
for the display is 5º up and 15º down.
The PNR was designed for fast installation. After drawing
the plumb line and installing the two top lag bolts into 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.
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 equipment.
• If you have any questions about this installation, contact Chief Manufacturing at 1-800-582-6480.

Swing Arm Tension Adjustment
Swing arm tension is pre-set at the factory and is
adjusted to accommodate displays with weights near the
top of the mounts capacity.
If smaller displays are used it may be difficult to
reposition the display after mounting. Swing arm tension
can be adjusted to compensate for smaller display by:
NOTE: The display must be mounted prior to adjusting
swing arm tension.
1. Locate the ajustment bar and wrench provided with
the mount.
2. Place adjustment bar into socket head cap screw
located at swing arm pivot point. (See figure 14)
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 15) and (See figure 16)
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.
