Using Push-in Posts
Landowners use push-in posts in situations where no animal will be leaning on or stressing the fence wires. This is accomplished by using an electrically charged wire on the fence that trains the animals to refrain from touching the fence. Using smooth wire or electric fencing tape with the posts along with a charger completes the package.
Push-in Post Advantages
Made of plastic or fiberglass, push-in posts are already electric insulators. This means a separate insulator, necessary for steel or wood posts, is not required. The posts are inexpensive when compared to other fence post types and require no tools for installation. These two factors make them ideal for temporary fence enclosures.
Push-in Post Disadvantages
The push-in post is really just a piece of plastic or fiberglass pushed into the ground. If an animal pushes on it, it will break of bend over. This can happen if the electric fence system fails and there is no charge on the wire to discourage the animals.
Push-in fence posts should be placed about every 15 feet in the fence line.Corner posts or posts where strain from the wire may occur should be braced using tent stakes, driving the tent stake into the ground about 4 feet to the outside of the fence. Tightening a wire between the top of the push-in post and the tent stake holds the post steady.
