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.
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.

M8 x 20 mm Hex Head Set Screws are recommended for schedule 40 (.203 wall) mast and
NOT RECOMMENDED for mast with a wall thickness less than 10 ga (.134) such as
Non-Penetrating Roof Mounts and Roof/Wall Mounts
.
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.
