CM300 Series Mounting Poles

1. General
The CM300 Series Mounting Poles provide a stainless steel 1.5 IPS vertical
pole for mounting sensors, enclosures, or other instrumentation. Pole length is
23”, 47”, or 56” for the CM300, CM305, and CM310 models respectively.
Mounting poles can be placed directly into a concrete foundation, attached to a
concrete foundation with the Pedestal J-Bolt Kit option, or can be selfsupporting with the Pedestal Leg options (F i gu res 1- 4) . A vinyl cap pre vents
precipitation from entering through the top of the pole.

3.2 CM300 Series Mounting Pole in Concrete Foundation
For permanent installations, CM300 series poles can be installed in a concrete
foundation. Dig a hole 6-8” diameter x 24” deep (or below frost level). Place
the pole in the center of the hole. Fill the hole with concrete, and plumb the
pole with a level.

3.3 CM300 Series Mounting Pole with Pedestal J-Bolt Kit
A CM300 series pole with the Pedestal J-Bolt Kit option can be used for
permanent installations where there is a need to periodically plumb the pole.
J-bolts are installed in a concrete foundation using the template provided with
the kit.
Construct a form 14” square (inside dimensions) from 2”x 4” lumber. Cut two
pieces of 2”x 4” lumber 18” long.
Dig a hole 14” x 14” x 24” deep (depth should exceed typical frost level).
Center, and level the form over the hole.
Install the J-bolts to the template using two nuts below the template, and one
nut above. Fill the hole and form with concrete, and place the two 18” 2”x4”s
on top of the form. Insert the J-bolts into the concrete, with the bottom of the
template resting on top of the spacers (template should be 2” above the
concrete).

CM300 Series Mounting Poles
Remove the template after the concrete has cured. Insert the pole into the
pedestal, and tighten the six bolts evenly.
Each J-bolt should have two nuts and one washer installed, with the bottom
nuts about 1/4” above the bottom of the threads. Place the pedestal over the
J-bolts and install a flat washer, split washer, and nut on each bolt – do not
tighten the nuts at this time.
Adjust the lower nuts on each J-bolt to plumb the pole. “Lock” the lower nuts
together using two wrenches. Tighten the upper nuts to secure the pedestal to
the J-bolts.

3.4 CM300 Series Mounting Pole with Pedestal Legs
A CM300 series pole with a Pedestal Leg option can be used for temporary
installations or for applications where a concrete foundation is not an option .
The “Short” Pedestal Legs are adequate for most applications. The “Long”
Pedestal Legs provide additional stability for applications where the feet cannot
be secured (e.g. to the surface of a roof), for extended poles, or for locations
with high winds.
Each leg attaches to the pedestal base with two bolts. The pedestal base has a
set of three holes for each leg. The angle of the legs, and resultant pedestal
height, is determined by which hole the end bolt is placed through (see table in
Section 2).
Attach the legs to the pedestal base, and tighten the bolts (do not over-tighten).
Place the pole into the base and tighten the six bolts evenly. For additional
stability, the feet can be spiked to the ground using (3) PN 17049 Ground
Spikes, or secured with user-supplied anchors through the holes in the feet.

PN 19238 grounding kit may be used to provide an earth ground for the
pedestal and associated instrumentation. Attach the earth and enclosure ground
wires to the lug on the pedestal base as shown in Figure 4.
