Don’t forget the drive caps! Prevent hammer damage to tops of posts by placing a protective drive cap on top of the post during installation. One drive cap lasts through years of uses and many posts. We recommend approximately one cap for every 20 posts ordered.

Benefits

Premier's SmoothCote FiberRods have a urethane coating to prevent fiberglass splinters from developing. (If you have not experienced these splinters, they're very painful as well as hard to spot.)


Specs

  • 3, 4, 5, 6 or 7 ft tall
  • 3/8" diameter
  • White in color
  • An extra UV resistant urethane outer coating to prevent fiberglass splinter
  • Pencil-pointed
  • Drive Caps (sold separately)
  • 20 per package, but priced individually. When ordering, please put in quantities of 20, 40, 60, etc.


Installation

  1. Attach a Drive Cap (sold separately) and drive the pencil-pointed end into ground with a hammer at designated area. If not using a drive cap use a rubber mallet so as not to create splinters on the post.
  2. Attach a SnapOn Harp Clip, ScrewOn Rope/Tape Insulator or PowerGrip Clip to the post.
  3. Insert twine, rope and narrow tape.


Tips

For easier installation of the SnapOn Harp Clip to the post, use a SnapOn Harp Clip Tool.

Listed below are recommended optional components or related items. Your particular situation may require alternative recommendations. Please call and talk to our consultants if there are any questions at 800-282-6631.

Excellent for line fences though 3/8" is not the best for corners or curves. (Upgrade to 1/2" posts in those situations.) Using a drive cap reduces wear on the post thus increasing its longevity. FiberRods last in the weather—hot or cold. (One of our employees used these in his line fence setup over winter to let his sheep graze an old pasture.)

I have used nearly 500 of these and they last so much longer than the step in posts that you can buy at the local ag store and they are so versatile in being able to adjust wire height. I use the spring clips with them and they make all the difference in the world. I use them with both polywire and 12.5 gauge high tensile wire on my perimeter fence and love them.

Posts are smooth coated so no glass fiber splinters. Nice point/taper. Drive cap fits to protect exposed end when driving. I used an earth drill to prepare to make driving easier.

These posts are SO much better for temporary fences than the step-in posts you can buy in the farm stores. If you’re changing fence lines and removing tape/rope on a regular basis, the farm store posts end up with the tape guides breaking and making the post useless. For a comparable price (sometimes cheaper) these posts with four ScrewOn Insulators have lasted longer, are more adjustable and more animal proof than any step-in posts I’ve had. They are also much better for added support and follow ground contours on mesh fencing better than the farm store step-in posts. I like these so much I’m now using with the 1/2" posts on semi-permanent fence lines.

About Conductivity

Conductivity measures the amount of electrical current a material can carry. The opposite measure is known as resistance.

Tinned Copper Superconductor

Many of Premier’s electric net fences feature a green and white superconductor that has both stainless steel and tinned copper filaments for optimal conductivity.

These “premium” nets are 10 times more conductive (38 ohms per 1000') than “basic” nets offered by our competitors. This enables the electric pulse to travel much farther and be less affected by weed contact.

Customers who are unhappy with netting are often those who’ve chosen nets from China or their farmstore equivalents.

Types of Line Posts

Line posts are built into the net. Three options are available.*

Line Posts Compared
  1. Single Spike (SS)
    The best choice, unless your soils are always soft or very hard.
  2. Double Spike (DS)
    Posts allow you to push in the spikes with your foot. When soil is hard or rocky, double spikes are more difficult to install and remove.
  3. Drivable Posts (DP)
    Allows use of a mallet or dead blow hammer for installing posts in dry, hard or rocky soil. Features a “spike stop” for extra support and internal fiberglass ribs for added strength.

Tip: To insert a line post into frozen or hard soil, use a power tool to drill pilot holes.

* Not all fences have all line post options.

About Positive/Negative (Pos/Neg) Nets

Is your area dry?

Conventional electrified fence systems rely on soil moisture to be effective. However, not all areas have the required moisture.

Dry soil increases resistance—a weaker, less effective pulse occurs that does not deter animals.

To overcome this, Pos/Neg nets* are wired to allow the use of every other horizontal strand as an extension of the ground terminal. Because half the strands are connected to the ground terminal or ground rod, reliance on soil moisture is reduced. A PowerLink must be purchased separately to make the secondary ground connection.

How it works…

In order to receive a shock, the animal must touch both a positive (hot) and negative (grounded) strand at the same time. This will deliver more pain to the animal than an all hot net (Pos/Pos) because moisture in the soil is not required to complete the circuit.

Pos/Neg fences can be converted to Pos/Pos in moist conditions. Remember, all fences must be kept free of vegetation.

* Not all fences have Pos/Neg options.

Line Post Spacing

“Plus” nets—6'8" spacings between built-in line posts*

Line Post Spacing

Standard nets—10' or 12' spacings between built-in line posts*

* Spacings are approximate.
Distance between built-in line posts may vary by product.

Essential Energizer Advice

  • Buy a larger energizer than necessary. When the fence pleases, most folks will buy more fence—and need additional output.
  • Use a low-impedance intermittent pulse energizer.
  • Use a fence tester to check the voltage often.
  • Use enough ground rod(s)—included with our energizer kits.
  • Don’t allow your lead acid battery to discharge below 40%.
  • Use insulated wire that is designed for electric fences.
  • Always connect the fence to an energizer, not an outlet.
  • Visit this link for answers to other common energizer questions.

Two Basic Types

  1. All-in-one Solar
    • Solar units are very portable.
    • Because they need a battery, these units are more costly to purchase and operate than plug-in units.
    • Batteries are less effective in cold temperatures (deplete faster).
    • Most farmstore solar units are too weak, in joules of output, to properly energize netting. That’s why we designed our own.
  2. Plug-in & Battery
    • Least cost to purchase and operate per joule of output.
    • Best for fences exposed to heavy vegetation.
    • Cold temperatures do not affect performance.
    • Recommended for whole-farm systems, but can be complex to install. Higher output requires more ground rods, underground cables, multiple output terminals, etc.

While at Iowa State University, Dr. Dan Morrical was responsible for educational programs in all areas of sheep production, ranging from nutrition, genetics, marketing and management. Research areas focused on applied projects in the areas of nutrition, forage utilization, genetics, out-of-season breeding and lamb survival.

Dr. Morrical has been heavily involved in providing educational resources to the sheep industry. He has authored over 30 extension fact sheets, ration balancing software programs, grazing videos and co-authored the nutrition chapter of the SID Handbook with Dr. Margaret Benson from Washington State University.

Dr. Morrical now serves as Premier’s on-staff small ruminant nutritionist and sheep production advisor. Most recently, he’s introduced a line of “GOLD FORMULA” mineral premixes under The Shepherd’s Choice® brand, aimed to maximize hoof health and immunity.

Braided vs. Twisted

Braiding instead of twisting the horizontals increases the frequency of metal filaments on the outside of the strand.

Braided vs. Twisted Electric Net Fences

What’s the benefit?

  1. More metal is exposed on the outside of the strand. This enables improved animal to conductor contact. The electric pulse is better able to travel from the fence and into the animal, resulting in a memorable shock.
  2. A tighter, braided weave results in fewer snags when carried or pulled through pastures, reducing frustration.
