STEP 6. Install a universal coupling on the lower end of
the uppermost section of the vertical operating
pipe in the fashion described above using
the ½ × 13 × 2½-inch bolt and ½—13 nut
provided. See Figure 9.
STEP 7. Position and install the guide-bearing assembly
on the pole in accordance with the dimension
shown on the erection drawing.
STEP 8. 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 9.
STEP 9. Repeat Step 7 if additional guide bearings are
speci ed. Intermediate sections of pipe are held
together using a splice coupling. See Figure10.
Insert the splice coupling inside the upper
section of pipe and align the holes. Insert the
ribbed neck carriage bolt through the pipe and
coupling and fasten with the supplied nut and
washer. Tighten the carriage bolt until the
ribbed-neck engages with the holes in both the
pipe and coupling. Then, insert the lower section
of the splice coupling into the next section of
pipe. Align the holes and insert the second
ribbed-neck carriage bolt through the pipe and
coupling, and fasten in the same manner as the
