Step 7
Install a universal coupling on the lower end
of the uppermost section of vertical operating
pipe in the fashion described above, using the

¹⁄₂
bolt and
¹⁄₂
—13 nut provided. See
Figure 6.
Step 8
Position and install the guide bearing assembly
on the pole in accordance with the dimension
shown on the erection drawing.
Step 9
Pass the next section of vertical operating pipe
up through the guide bearing and attach it to
the universal coupling on the lower end of the
uppermost vertical-operating-pipe section. See
Figure 6.
Step 10
Repeat Steps 7 and 8 if additional sections of
vertical operating pipe and guide bearing assem-
blies are specified. These additional sections of
vertical operating pipe will be joined with rigid
couplings rather than universal couplings. See
Figure 7. Make certain the cutting tips of the
piercing set screws in the rigid coupling do not
protrude through the body of the coupling when
inserting sections of vertical operating pipe into
the coupling. After the pipe is in place, torque
the clamp bolts to final tightness; then tighten
the associated piercing set screws, piercing the
pipe, and continue turning until a firm resistance
is felt.
