1. General
The CM110 (10 feet), CM115 (15 feet), and CM120 (20 feet) tripods are
corrosion-resistant aluminum instrument mounts that support the attachment of
sensors, solar panels, and environmental enclosures. The tripods are shipped
with brackets for the attachment of enclosures, and UV-resistant cable ties for
securing cables. A guy kit is included with the CM115 and CM120 models,
and is an option for the CM110. A durable Tripod Tote Bag is also available
as an option.

4. Tripod Components
Figure 4-1 shows the tripod components packaged for shipment. The tripod
base is packaged with the mast, ground rod, lightning rod and (6) stakes. The
ground rod clamp, lightning rod, and grounding wires are enclosed in a bag.
The guy kit (optional for the CM110), and tripod tote bag (optional) are
packaged separately. The CM115 and CM120 tripods include additional mast
sections. A diagram showing how to stow the components inside the tote bag
is shown in Appendix A.

5. Tripod Installation
5.1 Tripod Base
Tripod installation near power lines is dangerous. The
minimum safe recommended distance from overhead
power lines is 2 times the height of the tripod and mast
combined. Call Blue Stakes to locate buried utilities
prior to installation.
All three models of tripods use the same tripod base. Each leg is adjustable,
which allows the tripod to be adjusted for non-level terrain.
Prepare the area where the tripod will be installed. The tripod requires an area
approximately 10 feet in diameter. Natural vegetation and the ground surface
should be disturbed as little as possible, but brush and tall weeds should be
removed.
Stand the tripod base up on end, and rotate the feet perpendicular to the legs.
Each leg has a slide collar with a black plastic T-bolt, and a spring loaded pin
that locks in holes located on the underside of the leg as shown in Figure 5-1.
Loosen the T-bolts and extend each leg until the pin engages in the center hole
(depress the tab to disengage the pin from a hole). With the legs extended,
orient the tripod so that the open channel of the tripod base faces North.

5.2 Mast
The CM110, CM115, and CM120 have one, two, or three mast sections
respectively. The bottom mast section has two hanger brackets for attaching an
instrument enclosure.
The top of each mast section has an insert that needs to be extended above the
mast. Remove the bolt and extend the insert 12 inches as shown in Figure 5-2.
Align the holes in the insert and mast, and replace the bolt.
FIGURE 5-2. Tripod Mast and Insert
The tripod base has three sets of slanted holes for attaching the mast; typically
the upper set is used. The mast is attached to the base with a pin, and secured
in the upright position with a locking bracket. Both the pin and the locking
bracket are attached to the base with lanyards.
To attach the lower mast section, hold the mast upright (with the enclosure
hangar brackets facing North) and align the hole in the bottom of the mast with
the slanted holes in the tripod base. Insert the pin through the holes, and rotate
the wire retainer over the end of the pin as shown in Figure 5-3A. The pin
should be in the bottom of the slanted hole when the mast is upright. Lift the
mast up so that the pin is in the upper end of the slanted hole (Figure 5-3B) to
allow the mast to be tilted down to a horizontal position.
