Install hog wire panels by spacing posts to match panel width, setting them in concrete, then fastening each panel with outdoor-rated screws or clips.
A hog wire fence sags when posts were spaced to the wrong width, and fixing that means pulling concrete. You can avoid the whole headache by learning how to install hog wire fence panels in three steps: match post spacing to panel size, set posts plumb in concrete, then fasten each panel taut.
The fence line starts before any digging: mark corners, gates, and the full run with stakes, string, or spray paint. Check local codes for height limits, setbacks, and permit rules at the same time — those are easier to fix on paper than after concrete is in the ground.
Plan The Line And Set Posts
Post spacing decides how straight and sag-free the fence stays, so it comes before everything else. Line posts should match the panel width: 6 ft panels get posts every 6 ft, and 8 ft panels get posts every 8 ft.
End, corner, and gate posts carry the most load. One landscape build using lighter 5 ft x 6 ft sections sat about 16 in below grade. The honest rule: adjust depth for your local frost line, soil conditions, and panel weight instead of copying a single number. In cold climates, go below the frost line so freezing soil can’t heave posts out of plumb; in sandy soil, deeper holes and a wider concrete collar hold better.
Hog wire panels are stiff, which is the point — anchored well, they hold a straight line under livestock pressure. That stiffness is also why spacing matters more than it does with woven wire: a 6 ft panel forced onto 7 ft spacing will bow, not stretch. Post spacing only works if the panels are already on site — if you’re still shopping, our roundup of the best hog fence panels compares sizes, wire gauges, and prices.
- Set each post plumb, checking both directions with a level.
- Hold posts with temporary braces so the concrete sets without shifting them.
- Pour the concrete, then wait 24–48 hours before attaching panels or rails.
When the concrete cures, a braced post should resist firm hand pressure with no visible lean.
| Post Role | Typical Depth | Spacing And Notes |
|---|---|---|
| End, corner, gate posts | 2 to 3 ft in concrete | Anchor the run and carry gate hardware |
| Line posts, 6 ft panels | 16 to 24 in | 6 ft apart |
| Line posts, 8 ft panels | 16 to 24 in | 8 ft apart |
| Lighter 5×6 ft sections | About 16 in | Spacing matches panel width |
| Long runs | 2 to 3 ft at corners | Add line posts every 8 to 12 ft |
| Wide gate openings | 2 to 3 ft | Extra bracing for vehicles and equipment |
How Do You Attach Hog Wire Panels To Posts?
Attach each panel with outdoor-rated screws through pre-drilled mounting holes, or use U-nails, heavy staples, brackets, or clips — and pull the panel taut before driving the final fasteners.
For preframed panels, align the panel between its posts, hold it with clamps or a helper, then fasten. Wooden posts and rails take screws or heavy staples best; brackets and clips suit metal posts.
Unframed mesh follows the same idea. Several builds frame the fence with 2×4 or 2×6 treated lumber for rigidity, and Perimtec adds tension wires top and bottom as a lighter alternative.
Check the top line with a string line or level before you finish. The panel should feel drum-tight, and the top should run level across the whole run. Wear gloves and trim or file sharp wire edges as you go.
Gates, Rails, And The Final Check
Install gates in framed openings with heavy-duty hinges and a secure latch, then walk the full line before you call the job done.
Plan wide openings if vehicles or equipment need to pass through. Temporary bracing stays in place until the concrete cures — usually 24–48 hours — because loading panels too early is what misaligns posts. At corners, overlap or splice panels so no gap opens where two panels meet.
Final run-through, in order:
- Confirm every panel is taut, with no sag between posts.
- Check that the top line stays level from end to end.
- Swing each gate: it should move freely and latch without binding.
- Re-seat or replace any fastener that was over-tightened.
- File sharp edges and confirm all panels are secure.
FAQs
How far apart should posts be for hog wire panels?
Match post spacing to the panel width. Panels that are 6 ft wide get posts every 6 ft, and 8 ft panels get posts every 8 ft. End, corner, and gate posts go deeper — typically 2 to 3 ft in concrete — because they carry the most load, while line posts at roughly 16 to 24 in usually suffice.
Can you attach hog wire panels without concrete?
You can fasten panels to existing posts or wooden rails with outdoor-rated screws, U-nails, or brackets, but the posts themselves need solid anchoring. Concrete is the standard because it keeps posts plumb and prevents the leaning that makes panels sag. In sandy or wet soil, skipping concrete is the fastest way to a crooked fence.
Do I need a top rail for hog wire?
Not strictly, but rails add rigidity and give the fence a finished top line. Many builders frame hog wire panels with 2×4 or 2×6 treated lumber, while others run tension wire top and bottom for similar stiffness with a lighter look. Either way, keep the mesh taut when you fasten it.
