Zareba Sure Shock Polywire Electric Fence Line - 1,320 ft Heavy-Duty Aluminum 3-Strand, UV-Stabilized

Zareba Sure Shock Heavy-Duty Polywire is a 1,320-foot temporary electric fence line laced with three aluminum conductors for a stronger, reliable psychological barrier for horses and livestock.

This heavy-duty polywire combines lightweight handling with robust conductive performance so you can set up, move, and repair temporary fencing quickly. The cord uses three highly conductive aluminum strands woven into PVC-coated, high-density fiberglass for UV resistance and enhanced durability. At 1,320 feet per reel, it’s sized for paddocks, rotational grazing segments, and short-term containment projects.

Why does aluminum conductor matter for an electric polywire?

Aluminum conductors transmit a stronger perceived shock than many standard stainless steel conductors, helping animals learn boundary limits faster. The three strands increase consistent conductivity along the line and reduce the chance of weak spots forming from single-point damage.

• Three aluminum strands for improved conductivity and consistent voltage transfer
• Delivers up to 20X stronger shock intensity compared with typical stainless steel polywire conductors
• Reduces behavioral testing by animals through a clearer deterrent

How durable is this polywire in outdoor conditions?

The core uses high-density fiberglass wrapped in UV-stabilized PVC, which resists sun degradation and mechanical wear better than uncoated alternatives. The construction also boosts tensile strength, which helps maintain line integrity during repeated setups and takedowns.

• PVC coating for UV protection and longer outdoor life
• Fiberglass core increases resistance to stretching and breaking
• Designed for multiple deployments without rapid deterioration

Is installation and maintenance simple for everyday users?

Yes — the lightweight reel and flexible construction make handling, splicing, and repairs straightforward in the field. You can unwind, wind back, and re-deploy the line quickly, which is ideal for rotational grazing or temporary containment.

• Easy to splice and repair on-site with basic tools
• Lightweight spool simplifies transport between pastures
• Quick setup allows fences to be erected in minutes

What are the product specifics and warranty coverage?

Each spool contains 1,320 feet of polywire and is intended for equine fencing, small livestock, and temporary pasture divisions. The manufacturer backs the line with a limited five-year warranty, providing additional confidence in material and workmanship.

• 1,320-foot reel size for large temporary runs or multiple smaller paddocks
• Three aluminum conductor strands woven into PVC-coated fiberglass
• 5-year limited warranty from Zareba

Who is this for: Zareba Sure Shock Heavy-Duty Polywire is built for horse owners, small-to-medium livestock managers, and farmers using temporary or rotational grazing systems who need a portable, visible fence line with higher conductive performance. It suits anyone who wants a fence that’s easy to move and repair but durable enough to withstand sun exposure and repeated use.
