FAQ
No. The height in the name is the mounting height, from finish grade to the top of the pole. The pole is longer overall because part of it is buried:
8, 10 and 12 ft poles: 3 ft longer (a 10 ft pole is 13 ft overall)
14, 16, 18 and 20 ft poles: 4 ft longer (a 20 ft pole is 24 ft overall)
25 ft poles: 5 ft longer (30 ft overall)
When replacing a direct burial pole, measure the height above ground, not the old pole's total length, and plan delivery and lifting for the overall length.
Set it so the buried length (3, 4 or 5 ft, see FAQ 1) is below finish grade. That puts the fixture at the listed mounting height and the hand hole and conduit entry where the drawing shows them. Hole size, backfill, compaction and whether to use concrete depend on your soil and local code, so have your contractor or a local engineer confirm them for your site.
Underground. A conduit entry slot sits in the buried section, 18" below finish grade, so bring your conduit in at that depth when you trench. Wires run up inside the shaft to a hand hole with cover, 14" above finish grade, for splices and service, and on up to the fixture. Sizes follow the shaft:
3" shaft: hand hole 1-5/8" × 3-1/2", conduit entry 1-5/8" × 3-1/2"
4" shaft: hand hole 2" × 4", conduit entry 2" × 4"
5" shaft: hand hole 3" × 5", conduit entry 2" × 4"
The whole pole is finished in polyester powder coat. For extra protection below ground, a coal tar epoxy coating is available as an option. It covers the entire embedded section plus 6" of shaft above grade, where moisture and de-icing salts collect at the ground line. It's recommended for wet or clay soils, irrigated areas, concrete backfill and sites where salt is used. For constant salt exposure, consider a fiberglass pole instead.
The pole is one piece and ships ready to set in the ground, with:
a removable pole cap
a hand hole with cover
a conduit entry slot in the buried section
your choice of drill pattern or tenon on top
There's no base plate, anchor bolts or base cover, because a direct burial pole doesn't use them. Fixtures, arms and brackets are sold separately.
Choose the pole top option that matches your fixture:
Drill mount for fixtures with an arm or bracket: drilled for 1 fixture (D1), 2 fixtures at 90° or 180° (D2), 3 fixtures at 90° or 120° (D3) or 4 fixtures (D4).
Tenon mount for slip-fitter and post-top fixtures: 2-3/8" OD × 4" (T2), 3" OD × 5" (T3) or 4" OD × 6" (T4).
Check your fixture's spec sheet for its mounting type and, for slip-fitters, the tenon size it fits. Round poles also allow 3 fixtures at 120° for even, all-around coverage.
Add up the EPA of every fixture, arm and bracket you plan to mount. Each one's EPA is on its own spec sheet.
Compare the total with this pole's EPA at your site's design wind speed. The total must be equal to or lower than the rating.
The cutsheet gives ratings at 80, 90, 100 and 120 mph, all with a 1.3 gust factor. Your local building code sets the design wind speed. If your total is too high, choose a shorter pole, a larger shaft or a 7 gauge pole.
Gauge is the steel wall thickness, and a lower number means thicker steel. 7 gauge (about 0.18") is about 50% thicker than 11 gauge (about 0.12"). At 25 ft, the 7 gauge pole carries roughly twice the EPA of the 11 gauge pole (9.2 vs 5.0 sq ft at 90 mph, 4.2 vs 2.0 at 120 mph) and weighs 290 lb vs 195 lb. 7 gauge is offered at 20 and 25 ft, where fixture loads and wind exposure are highest.
The shaft is a one-piece, uniform-wall tube of ASTM A500 Grade B carbon steel, 46,000 psi minimum yield, finished in polyester powder coat. There are no welded base parts, since the buried section anchors the pole.
