How to Install Cattle Fence | Start With The Corners

Installing cattle fence starts with a property check, then strong corner braces, posts, and proper tensioning.

The right way to install cattle fence comes down to planning the line and building solid corners before you stretch a single wire. A fence is only as strong as its end assemblies, since corner and gate posts carry the most load. Measure your property lines, call for utility locates, and pick a fence type before you dig.

That first hour of planning saves a full day of rework. Below is the practical order of work, pulled from USDA and Tennessee Extension guidance, that holds up on real farms.

Plan The Line And Brace The Corners First

Walk the property line with a map and mark the corners, gates, and any changes in elevation. Call your local utility locating service before any digging — hitting a buried line is a safety risk and an expensive mistake. Only after the line is marked do you choose materials, based on whether you need woven wire, barbed wire, or high-tensile fence.

Corner and gate posts carry the most load, so underbuilding them weakens the whole fence. USDA guidance calls for H-braces or welded angle braces on every fence except one- and two-wire electric systems. Use 6-inch to 8-inch wood posts or 2-inch to 3-inch steel posts set in concrete, sunk 24 to 36 inches deep.

Brace spacing matters as much as the posts themselves. USDA’s fence fact sheet specifies full brace assemblies every 660 feet for woven wire, 1,320 feet for barbed wire and barbless cable, and 2,640 feet for high-tensile fences.

Set Line Posts At The Right Depth And Spacing

Line posts are commonly spaced 10 to 12 feet apart for barbed wire or high-tensile fencing. Driven T-posts should go 18 to 24 inches deep, while corner and gate posts should sit at least 3 feet deep. Drive each line post so the fence line stays straight — a post that leans or sits off-line makes tensioning harder later.

When the line runs straight, string a guide line between the corner braces and set every post to the same height along it. On uneven ground, step the posts down gradually rather than forcing one long slope.

Unroll, Stretch, And Attach The Wire

Tennessee Extension’s fence publication gives the practical sequence: secure the wire to the corner, end, or gate posts first, then secure the bottom wire to each line post as you work down the line. This keeps the wire positioned correctly and helps confirm the next post sits where it should.

Unroll the wire along the fence line, keeping it off the ground to avoid snags. Pull it hand-tight past the first brace, then use a come-along or fence stretcher to reach final tension. Over-tensioning pulls posts out of line; under-tensioning lets the fence sag and fails to hold cattle.

Fasten Panels And Finish The Job

For panel-based cattle fence, attach the first panel to the corner post with three clips at the top, middle, and bottom. Adjacent panels overlap 6 to 12 inches and share a post, which keeps the line continuous and stiff. Work panel by panel down the line, checking that each one sits plumb before you drive the next clip.

Finish by walking the full line to catch loose clips, sagging wire, or posts that shifted during tensioning. Tighten anything that moved before you call the job done. That final walk-through is what separates a fence that holds for a decade from one that needs constant patching.
