Why a Taut Poultry Net Fence Matters Most
A sagging net is a failed fence. Chickens, being curious and persistent, will quickly discover a low spot to slip under or a loose section to push through. More critically, a predator like a fox or raccoon sees that same sag as a weak point to exploit, easily climbing over or digging under.
The problem goes beyond simple containment. If you’re running an electric net, a droopy top line can easily touch a metal T-post or wet grass, shorting out the entire system. You think your fence is hot, but it’s completely dead, offering zero protection. A taut fence keeps those hot lines suspended in the air where they belong, delivering a consistent and effective shock.
Ultimately, proper tension is about longevity and less work for you. A fence that’s consistently tight puts even strain on the posts and the mesh, preventing premature wear and tear. It also stays clear of your mower deck and is far less likely to get tangled, saving you countless headaches over the season.
Gallagher In-Line Ratchet Strainer: The Gold Standard
Tighten and maintain your electric or farm fence easily with these 10 heavy-duty inline wire tensioners. The ratchet design simplifies wire adjustments for optimal fence performance.
When you want to set your fence tension and not think about it again for a long, long time, you get a Gallagher. These things are the gold standard for a reason. They’re built from heavy-duty, galvanized steel and have a simple, robust ratchet mechanism that just doesn’t fail.
The design features a split spool that makes it easy to start your wire or poly-rope, and the gear system gives you incredible mechanical advantage. You can achieve a level of tension with a Gallagher handle that’s impossible by hand. This allows you to pull long, straight runs of netting incredibly tight, eliminating sag from one end to the other.
The tradeoff is cost and the need for a separate tensioning handle. But this is a classic "buy once, cry once" situation. For a permanent or semi-permanent pasture perimeter where you can’t afford any weakness, the holding power and durability of the Gallagher are worth every penny. It’s a professional tool for a farmer who values reliability above all.
Zareba Corner Post Insulator/Tensioner Combo
Corners are where fence tension lives or dies. All the force of a tight line converges there, and it’s also where you need solid insulation. The Zareba combo unit cleverly solves both problems at once, making it a fantastic choice for setting up a sturdy perimeter.
This device functions as both a secure anchor point and a tensioner. You wrap your polywire or rope around the spool, and a simple mechanism—often a wing-nut or a slot for a wrench—allows you to crank it tight. Because it’s also a robust insulator, you don’t have to worry about the current leaking into your wood or metal corner posts.
This is a brilliant solution for semi-permanent setups. If you’re rotating poultry through several paddocks defined by T-posts and sturdy corner posts, these combos streamline your setup immensely. They reduce the number of components you need at your most critical points, leading to a cleaner, stronger, and more reliable electric fence.
Dare T-Post In-Line Strainer for Durability
Long runs of poultry netting will sag in the middle, no matter how tight you pull the ends. That’s where an in-line strainer comes in, and the Dare models designed for T-posts are some of the toughest around. They are built for the field and can take a beating.
These strainers are often designed to clip directly onto a standard T-post, which is a huge convenience. You simply cut your polywire, thread both ends into the strainer, and start cranking. This allows you to add a tensioning point anywhere along your fence line, breaking a long, saggy run into two shorter, tighter sections.
Made from heavy-gauge, rust-resistant metal or extremely tough UV-stabilized plastic, these are workhorses. They aren’t as refined as a Gallagher ratchet, but they don’t need to be. Their job is to hold tension in the middle of a field, year after year, and they do it exceptionally well.
Fi-Shock In-Line Strainer: A Reliable Budget Pick
You don’t always need the most expensive, over-engineered tool for the job. For smaller chicken runs, temporary fencing, or internal paddock divisions, the simple Fi-Shock in-line strainers are a smart, cost-effective choice. They prove that you can get a tight fence without breaking the bank.
These are typically made of high-impact, durable plastic with a simple wing-nut or knob design. You thread the polywire through, turn the knob, and it locks in place. It’s a straightforward mechanism that provides more than enough tension for a 50 or 100-foot roll of poultry netting.
Are they going to last 20 years like a galvanized steel ratchet? Probably not. But they are inexpensive, lightweight, and incredibly easy to install without any special tools. For a hobby farmer managing a few different areas, having a handful of these on hand is a no-brainer for quick repairs and setting up temporary enclosures.
Parmak Heavy-Duty Ratchet for Large Pastures
When you move from a backyard run to pasturing birds across an acre, the physics of your fence line change dramatically. A small plastic strainer just won’t cut it. The Parmak Heavy-Duty Ratchet is built for these large-scale applications where you need serious pulling power.
Think of this as the bigger, tougher cousin of other ratchets. It’s designed to handle the significant load of several hundred feet of wire or heavy-duty poly-rope. The all-metal construction and larger spool are engineered to withstand the constant, high tension required to keep a long fence from drooping in the middle. It’s the kind of tool you need when you’re stretching a perimeter around a whole field.
This is definitely overkill for a small coop and run. But if your poultry rotation involves long, straight fence lines, investing in one or two of these for your main anchor points is essential. It provides the raw strength needed to get the initial tension right, which is the foundation of a good large-scale fence.
Kencove Compression Spring for Constant Tension
This is a piece of equipment that separates the amateurs from the old pros. A compression spring isn’t a tensioner itself, but a tension manager. It’s the secret to a fence that stays tight through a blazing hot summer and a frigid winter without constant adjustment.
You install the spring in-line with your fence wire, usually near an anchor post. After you’ve tightened the fence with your primary ratchet strainer, the spring sits under tension. As the temperature changes, the fence wire expands (sags in the heat) and contracts (gets banjo-tight in the cold). The spring absorbs these changes, expanding and compressing to maintain a steady, ideal tension on the line.
This simple device is a game-changer for electric fence reliability. By preventing the wire from getting too loose or too tight, it ensures your fence voltage remains consistent and dramatically reduces wear and tear on your insulators and posts. It’s a small addition that saves a ton of maintenance work down the road.
Proper Tensioner Installation for a Drum-Tight Fence
The world’s best tensioner is useless if your anchor points are weak. Your corner posts are the foundation of your entire fence. They must be solid, deep-set, and preferably braced. A single T-post pounded in at a corner will simply bend over the moment you apply real tension.
For a basic installation, place your tensioners at the end of a run, attached to your well-braced corner or end posts. Pull the netting as tight as you can by hand first, removing all the initial slack. Then, begin tightening the ratchet or strainer, turning it a few clicks at a time. Walk the fence line as you go to make sure the net isn’t snagged on a rock or clump of grass.
The goal is a fence that is taut to the touch, with minimal sag between posts. You don’t need to tighten it so much that it hums like a guitar string; over-tightening can damage the netting and pull up your posts. For runs longer than about 200 feet, installing a second in-line strainer in the middle is crucial for eliminating that inevitable mid-point droop. Check the tension every few weeks and especially after heavy rain or wind—a tight fence is a working fence.
A sagging poultry net is a problem waiting to happen, but it’s one of the easiest to solve. By choosing the right tensioner for your scale and setup—from a simple budget strainer to a heavy-duty ratchet—you invest directly in the safety of your flock and your own peace of mind. A tight fence does its job, so you can focus on yours.
