6. Electric Fence Posts Guide
We stock a good variety of fiberglass posts, plastic step-in posts, studded steel T-posts, and steel U-posts. With a push and a shove, all these posts can be used interchangeably; but certain ones do certain jobs best. Step-in posts (secured at corners and sharp bends with tent pegs) do well in temporary fences or ones that must frequently be moved about (see products 09-11 thru 09-14, 09-99, 09-100, and 09-105). Studded steel T-posts (commonly placed in cement footings and secured by earth anchors) play a key role at the corners, ends, and gates of permanent high-tensile fences (see product 09-23A). Shorter T-posts and U-posts work best at the corners, ends, and gates of low baited electric fences (see products 09-19 thru 09-21 and 09-30 thru 09-32). However, the workhorse of electric fences is the fiberglass post—which is easily installed, long-lived, tough, and well-suited to performing the duties of a line post, where its flexibility is no problem. Low baited electric fences generally use 3/8-inch or half-inch fiberglass posts (products 09-04 thru 09-08), while tall high-tensile fences typically use 11/16-inch fiberglass posts supplemented with plastic battens. For examples of these various types of fences and their posts, see About 1-Wire Kits and About High-Tensile Kits together with associated drawings and parts lists.
Other posts and supports sometimes used with electric deer fences include wood posts, chain link fences, and trees. In using chain link fence (and also metal posts) as a support, one must keep in mind that steel is an avid conductor, and so one needs to rigorously avoid any contact between the posts or the chain link fence and the electrified wire. Regarding wood posts, beware of any that are not chemically treated or massive, because the expected life of untreated wood in the soil is very short. Also, wood is not nearly so good an insulator as fiberglass, so one needs to avoid contact between the wood posts and the electrified wire. If one wishes to simply nail electric fence insulators onto trees and support the conductor that way, this can be done. However, trees are not insulators at all (they are full of sap); so one must carefully avoid contact between the conductor and tree trunks or branches, and also between the conductor and those trunks to which the insulators are attached.
