How to Build a High Tensile Fence

High-tensile fences are a simple, inexpensive solution to providing a fence for most kinds of livestock. They require five to eight wires in order to be most effective in containing livestock and deterring predators. Many livestock owners add a fencing energizer to electrify every other wire, a simple upgrade that makes this type of fence even more secure. Even if you don't choose to electrify your high-tensile fence, it still provides a very affordable, easy-to-install fencing option that lasts for years with minimal maintenance.

Things You'll Need

• Posts Brace post poles Brace pins Chalk 12.5-gauge wire Fence cutters Hammer 2-inch galvanized staples Wire clips Fencing pliers Ratchet-type strainers Tension springs

Instructions

1. Install post brace assemblies on your fence anchor posts. Anchor posts are all corner, end and gate posts, as well as one wooden line post for every 200 feet of straight fence you are installing. Each anchor post must have an accompanying brace post inserted into the ground along the fence line at a distance of 8 feet. Drill a 3/8-inch hole about 12 inches from the top of each of the two posts. Insert a brace pin into each hole and attach the 8-foot post brace pole to the pins. This creates an H-brace, named for the shape that it creates.

2. Determine the height of your high-tensile fence and the number of strands of wire you desire. For basic security, you will want a fence that is at least 42 inches tall and has five wires at minimum. Space your wires about 6 to 9 inches apart, with the bottom wire approximately 6 inches from the ground. Mark each corner post with chalk to show your chosen wire spacing.

3. Install the bottom wire first. Knot the wire to the first anchor post and run it to the next anchor post. Knot the wire and start over again at each anchor post. This maximizes the strength of each section of fence. Repeat this process for each wire.

4. Attach the wires to the line posts. Use galvanized 2-inch staples for wood line posts. Attach the high-tensile wire to metal posts using fencing pliers and wire clips. Be sure the wire can still slide easily through the staples and clips so you can adjust the fence tension.

5. Adjust the fence tension. Install in-line ratchet-type strainers on each wire. Install the strainers in the middle of the longest straight stretch of fence. Adjust the tension, tightening until the fence is no longer slack. If the wires are sagging or touching each other, the tension is not tight enough.

Tips & Warnings

• Tighten the wire one to two times per year to ensure top working condition. Inspect the fence on a regular basis so you can pinpoint areas that need to be repaired as soon as possible.

• Wear goggles and gloves when tightening the tension on the fence to prevent damage to your eyes or hands if the wire breaks.
