Guide to Wooden Post Fence Installation

Materials Needed

Wooden posts: Pressure-treated or naturally durable (e.g., cedar, oak), 4–6 inches diameter, 6–8 feet long, depending on fence height and soil conditions.HT wire, barbed wire or electric fence wire/rope/tape.
Staples: Galvanized U-shaped fence staples, 1–2 inches or Electric/Pneumatic Fencing Gun
Gripples or crimp sleeves: For wire joining and tensioning
Concrete mix (optional): For securing corner/end posts in loose soil
Post caps (optional): To protect post tops from rot

Post hole digger or auger: Manual or powered for digging post holes.
Fence pliers or Strainrite Staple Remover For stapling and wire cutting
Gripple tensioning tool or Strainrite ratchet strainer: For wire tensioning
Fence tester or Tension Tester
Level: To ensure posts are vertical
Tape measure and string line or Rotosure Measuring Wheel For accurate post spacing ($5–$15).
Sledgehammer or post driver: For driving posts
Shovel and tamping bar: For backfilling and compacting soil
Gloves and safety glasses: For protection.
Chainsaw or saw or Strainrite Chisel: For trimming posts

Mark the fence line:
Determine post spacing: Space line posts 8–12 feet apart for high-tensile or barbed wire, or 15–20 feet for electric fences. Place corner/end posts and gate posts at key points.
Check regulations: Verify local zoning laws or livestock fencing requirements (e.g., minimum height for cattle is 48 inches).

Dig holes: Use a post hole digger or auger to dig 2–3 feet deep (1/3 of post length) and 10–12 inches wide for corner/end posts, which bear the most tension.
Set posts: Place posts in holes, ensuring they’re vertical with a level. For high-tension fences, brace corner posts with H-braces (diagonal supports) or cross-bracing.
Secure posts: Backfill with soil, tamping every 6 inches for stability. In loose or sandy soil, use concrete (mix per instructions, allow 24–48 hours to set).
Tip: Angle corner posts slightly outward (5–10 degrees) to counter wire tension.

Dig or drive posts: Dig holes 2–2.5 feet deep for line posts, or drive posts directly into firm soil using a sledgehammer or post driver. Ensure posts are vertical and aligned with the string line.
Spacing consistency: Measure distances to maintain even spacing. For example, 10-foot spacing ensures 8–10 posts per 100 feet.
Depth check: Ensure 1/3 of the post is below ground (e.g., 2 feet for a 6-foot post) to withstand wire tension and livestock pressure.
Tip: Trim posts to uniform height with a saw if needed, and add post caps to prevent rot.

Choose wire type: Use high-tensile wire for durability, barbed wire for livestock deterrence, or electric wire/rope/tape for containment with minimal maintenance.
Start at corner posts: Secure the wire to a corner or end post using staples or a Gripple. Drive staples diagonally to avoid splitting wood, leaving 1/8 inch of play to allow wire movement.
Unroll wire: Pull the wire along the fence line to the next corner/end post, keeping it taut but not fully tensioned yet.
Attach to line posts: Staple the wire to line posts at the desired height (e.g., 12–48 inches for livestock, spaced 6–12 inches apart for multiple strands). Ensure staples are snug but allow wire to slide slightly to prevent stress.
Tip: For electric fences, use insulators instead of staples to prevent grounding.

Use a tensioning tool: For high-tensile wire, use a ratchet strainer or Gripple tensioning tool to achieve 200–250 pounds of tension (check with a tension gauge). For electric fences, lighter tension (50–100 pounds) is sufficient.
Tension in stages: Tighten each strand incrementally, checking alignment and avoiding over-tensioning, which can damage posts or wire.
Join wires if needed: Use Gripples or crimp sleeves for secure, conductive joins (as described in prior responses). Avoid knots for permanent installations.
Tip: Tension bottom wires first to maintain even pressure across strands.

Check alignment: Ensure posts are vertical and wires are evenly spaced and taut.
Test electric fences: Use a fence tester to confirm voltage (e.g., 4,000–6,000 volts for cattle). Check for shorts caused by loose staples or vegetation.
Secure loose ends: Trim excess wire and secure with staples or Gripples.
Inspect posts: Ensure no staples are driven too deeply, causing wood splits. Remove and reposition if needed (see prior response on staple removal).

Regular checks: Inspect the fence every 3–6 months for loose wires, staples, or post damage. Re-tension wires as needed, especially after temperature changes.
Clear vegetation: Trim grass or weeds to prevent grounding in electric fences or rot in wooden posts.
Replace damaged components: Swap out cracked posts or corroded wire promptly to maintain fence integrity.

Soil type matters: In clay or rocky soil, driving posts may be faster than digging. In sandy soil, concrete is essential for corner posts.
Safety first: Wear gloves and safety glasses when handling wire or driving staples to avoid cuts or splinters.
Livestock considerations: For cattle, use 4–5 strands of barbed or high-tensile wire at 48–54 inches high. For sheep, add closer-spaced wires near the ground to prevent escapes.
Cost efficiency: Bulk-buy materials (e.g., wire rolls, staples) to reduce costs. For example, a 1,320-foot roll of high-tensile wire covers a quarter-mile of single-strand fencing.
Gripple advantage: As noted in prior responses, Gripples simplify tensioning and repairs, saving time for large installations.

Post misalignment: Use a string line and level during installation to ensure straightness. Correct leaning posts by re-digging or bracing.
Wire sagging: Re-tension wires using a Gripple tool or strainer. Check for weak posts that may need replacement.
Wood splitting: Avoid over-driving staples; use a lighter hammer or pre-drill staple holes in hardwood posts.
Electric fence failure: Test for voltage drops caused by poor joins or grounding. Use rope connectors or tape buckles for reliable electric fence repairs (see prior responses).
