Recommended Accessories for Pole Mounting
• Use the Mounting Tripod (#7716) for easiest mounting.
• Use the Mounting Pole Kit (#7717) to raise the installation height of the ISS by up to
37.5" (0.95 m).
General Guidelines for Installing on a Pole
• With the supplied U-bolt, the ISS can be mounted on a pole or rod having an outside
diameter ranging from 1" to 1.75" (25 – 44 mm).
• To mount on a smaller pole, obtain a U-bolt that fits the base openings but that has a lon-
ger threaded section. If mounting the ISS on a smaller pole with the included U-bolt, the
threaded sections of the U-bolt will be too short to securely mount the ISS.
Installing the ISS on a Pole
1. If you are mounting your ISS on a Davis Mounting Tripod or the pole included with a
Davis Mounting Pole Kit, follow the instructions included with those Davis products for
proper installation.
If you are not using one of these Davis products, mount on a galvanized steel pole having
an outside diameter ranging from 1" to 1.75" (25 – 44 mm).
Note: It is important that the mounting pole be plumb. You may wish to use a level such as a magnetic ”torpedo
level” to assure that the ISS, when mounted on top of the pole, will be level.
2. Using the illustration above as a guide, hold the ISS so that the wind cups and radiation
shield are on the left and gently place the ISS on top of the pole.
3. While holding the mounting base of the ISS against the pole, place the two ends of the U-
bolt around the pole and through the two holes in the C-shaped bracket on the base.
4. Slide the metal backing plate over the bolt ends where they extend out from the far side of
the bracket.
5. Secure the backing plate with a lock washer and hex nut on each of the bolt ends, as shown
in the illustration.
6. Tighten the hex nuts with your fingers only so that the ISS is just secure enough on the
pole for you to release your grip.
