G: FIVE STRANDS ELECTRIC ROPE
Where animals are on both sides of a fence, nothing commands fence respect like five
strands of electric rope. Horses, cattle, sheep, pigs, dogs, and emus will look, but not
touch more than once. And even without electricity, it is an effective physical barrier.
Posts
Although the type of posts that you use will depend on the style of fencing you choose,
some information about posts relates to nearly all fencing systems.
Wooden posts are used with many other types of fencing besides plank and rail. Wooden
posts are 6 to 10 feet long and are set 2 to 4 feet in the ground. Postholes are dug or drilled
and the posts are set with tamped native soil, gravel, and often cement. If the ground is not
too rocky, wooden posts can be driven into the ground using a mechanical post driver.
Preservatives are applied according to standards for use aboveground, with ground con-
tact, or as a foundation (below the ground). It is important that fence posts are treated
adequately for use below the ground. Four-by-four landscape timbers, although less ex-
pensive, are treated for ground contact, not for below-the-ground (foundation) applications.
Each post or piece of treated lumber should have an ink stamp or plastic tag stapled to it
that specifies the level of treatment, the intended use, the treating plant and date, and a cor-
poration guarantee or the logo of an accredited inspection agency.
Posts are generally available in 2- to 8-inch diameter; the size refers to the diameter of
the small end. Corner posts and gateposts should be 8 inches in diameter; brace posts at
least 4 inches; and line posts at least 3 inches.
