Jackleg Fencing

The Montana classic. Jackleg (buck-and-rail) fencing needs no post holes, so it goes up on rocky ground, steep grades, and even frozen soil — and it looks like it belongs here.

The Fence That Was Made for This State

Drive any road in Paradise Valley or the Gallatin Valley and you’ll see jackleg fence — sometimes called buck-and-rail — lining ranches that have used it for generations. There’s a reason it never went out of style: jackleg fencing doesn’t need post holes.

Instead of setting posts in the ground, jackleg fence rests on crossed-leg “bucks” that sit on the surface. That means:

  • It works where other fences can’t. Rock ledge, shallow soil, river rock, steep grades — if we can walk it, we can fence it.
  • Frost can’t heave it. Montana’s freeze-thaw cycles push set posts out of the ground over time. Jackleg just rides on top.
  • It goes up year-round. Frozen ground stops post pounding cold. It doesn’t stop a jackleg build, which makes winter a smart time to schedule one.
  • It looks right. Nothing says Montana ranch like a jackleg line running toward the mountains.

Bark-On or Treated — Your Call

We build jackleg two ways:

  • Bark-on jackleg keeps the natural bark intact on posts and rails. The look is as rustic and authentic as it gets, and the bark acts as a natural protective layer.
  • Treated jackleg uses pressure-treated wood for the longest possible service life against rot, insects, and weather — the right choice for wet ground and hard-working fence lines.

Either way, the construction is the same: solid bucks set at consistent intervals, rails lapped and fastened to stay put under snow load and livestock pressure, and straight lines even across broken ground.

Built for the Job It Has to Do

A boundary fence, a horse pasture, an elk-pressured hay yard, and a decorative entrance line are four different builds. When we walk your property we’ll talk through:

  • What the fence needs to contain (or keep out)
  • Rail count and height for your animals and wildlife pressure
  • Wire additions for dogs, sheep, or garden protection
  • Gates, cattle guards, and equipment access
  • How the fence ties into your entrance and archway if you want the whole front of the property to work together

Local Crew, Local Wood

We’re based in Bozeman and run our own sawmilling operation, so much of the timber in our fences is cut here in Montana. Our crew has built jackleg across Gallatin and Park counties — Bozeman, Livingston, Emigrant, Pray, Gardiner, Big Sky, Big Timber — on working cattle ranches, horse properties, and luxury homesites alike.

Jackleg Fencing — Questions We Hear a Lot

Why is jackleg fencing so common in Montana?

Because it solves Montana problems. The A-frame 'buck' design sits on top of the ground instead of in it, so you can fence across rock, shallow soil, steep grades, and river bottoms where digging or pounding posts is impractical. It also handles frost heave better than set posts.

Can jackleg fence be built in winter?

Yes — that's one of its biggest advantages. Since no posts go into frozen ground, jackleg is one of the few fences we can build nearly year-round in Montana.

What's the difference between bark-on and treated jackleg?

Bark-on jackleg keeps the natural bark on the posts and rails for a rustic look and a natural protective layer. Treated jackleg uses pressure-treated wood for maximum resistance to rot, insects, and weather. Both are built the same way — the choice is about look and longevity priorities.

Will jackleg hold livestock?

Properly built jackleg with the right rail count contains cattle and horses well, and it's often paired with wire for smaller animals. Tell us what you're containing and we'll spec the build accordingly.
