POLE SPECIFICATIONS:

Ground Pole “A” = 3.00 O.D. x 10 G.A. x 72” Steel

Ground Pole “B” = 2⁷⁄₈ O.D. x .203 Wall x 72” Steel ASTM 120 Mech Tubing (2¹⁄₂ Sch. 40)

NOTE:

Pole not supplied and must be field drilled ⁵⁄₈” dia. for #3 rebar and drilled .218 for ¹⁄₄-20 self tapping grounding screw (see Page 7) and galvanized or painted for protection.

1 - Pole and foundation design based on the following criteria:

a)Uniform building code exposure B or C and 1.5 stability factor.

b)Vertical soil pressure of 2000 pounds per square foot.

c)Lateral soil pressure of 400 pounds per square foot.

d)Concrete compressive strength of 2500 pounds per square inch in 28 days.

Once fine tuning is complete and all Clamp Bolts are equally torqued to 18 ft-lbs. in accordance with 8000842 manual, then install the two M8 x 20 mm Hex Head Set Screws supplied. Install one in each clamp half as shown in Fig. 1.0. Torque each M8 x 20 mm Hex Head Screw to 15 ft-lbs. Repeat torque to insure 15 ft-lbs. has been reached on both screws.

See Manual 8000842 for additional instructions not shown here.

2 - CAUTION - The foundation design shown does not represent an appropriate design for any specific locality since soil conditions vary and may not meet design criteria given in Note 1. You should consult a local professional engineer to determine your soil conditions and appropriate foundation.
