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).
