with coupled lengths of conduit or pressure pipe. Limitless
variety of custom-made uprights can be erected below usual
costs. Adapted to small or large quantities. Attractive
design of tough cast iron; hub tapped deep for strong, locking

conduit stubs; the 4" base opening permits four 1 1/4"
stubs.

| Many
lighting installations will be at relatively low elevations
of 8, 10, or 12 feet, for fixtures of the post-top variety,
of 1 .0 square feet or less. Here, 2" galvanized conduit
with HOPE Base H42200-2" can safely be recommended for
fixture elevations up to 12 feet in the EAST COAST, or 14 feet
INLAND to WEST. |
For
higher elevations where coupled lengths of conduit will be required,
the critical pipe and base size will be that for the lowest
section of the pipe where loading is greatest. The upper pipe
column can be smaller sized conduit as loading is less. A typical
Problem and Solution is given below the table. |

1)
a few local spots in the Gulf area have had
maximum winds greater than those of the East Coast. For these,
Key West, Mississippi delta, Galveston to Brownsville, use East
Coast elevations decreased by 20%.
PROBLEM: An East Coast installation will require a 2
square foot fixture elevated to 18 feet. What size of Base,
lower section pipe, and upper section pipe can be specified. |
Solution:
Checking down the fixture size column, we find that the smallest
conduit to handle 2 square feet at 18 feet is the 3" (allowable
to 19’). This means that the lower pipe section must be
3" conduit, with an H42300-3" size Base, and a standard
length of 3" is ten feet. For the remaining upper 8 feet,
2" conduit will handle this safely, so the overall pole
will consist of H42300-3" HOPE Base, ten feet of 3"
conduit, 3" x 2" reducing coupling, and 8 feet of
2" conduit. |
