Product Description

wire-gauge-chart2.jpgThis is a 500 foot roll of Heavy Duty - Solid Core Pet Fence Wire and it's available in Four Thicknesses: 20 Gauge, 18 Gauge, 16 Gauge and 14 Gauge. No matter the terrain you are enclosing, we have the heavy duty wire you will need. These 500 foot rolls are enough wire to enclose up to 1/3 to acre. We recommend Heavy Duty Pet Fence wire in any areas where the wire may experience wear and tear such as rocky conditions or cold weather climates.

Electric dog fences usually come with 20-gauge (thinnest), 18-gauge, 16-gauge, or 14-gauge (thickest) wire. The 20-gauge wire with a vinyl coating is what you will find in most pre-packaged do-it-yourself fencing kits. Most professionally installed systems use the more substantial 14, 16 or 18 gauge wire. Whether you’re replacing a section of your existing fence or wiring your yard from scratch, you can easily find a relatively inexpensive and compatible wire for your project. Regardless of gauge, you should choose only a solid insulated wire rated for burial preferably polyethylene or plastic coated works best.All of our wire use these coatings for maximum performance.

This wire is compatible with all PetSafe®, SportDOG®, Innotek®, Invisible Fence® Brand, Dog Watch® PetStop®, Contain Your pet®, Dog Guard®, Perimeter® Brand, Dogtek®, Dogtra®, Guardian®,  Havahart® and all other brands of in-ground electric dog fence systems.

Factory Grade Wire

This is the wire included in all self-install kits. Regardless of gauge, this wire is of medium quality, lighter weight and keeps shipping and initial costs down. This wire will work but does not hold up to the elements as well as a professional grade wire. The vinyl wire coating is prone to cracks and over time exposes the copper leaving the wire susceptible to damage. This can cause issues that impact the functionality of your dog fence system. Since finding, digging up, and repairing wire breaks can be a tedious job at best, many people prefer to upgrade to a pro-grade wire from the start.

The initial cost of heavy duty grade wire is a bit more than manufacturer grade wire. However, there are many benefits to choosing heavy duty wire for your dog fence. Heavy Duty grade dog fence wire holds up better to freezing conditions, sunlight exposure, contraction and expansion of the ground, water exposure and general wear and tear. The long term savings in time and replacement if you are planning on staying in your home for at least a year or more, makes the heavier duty wire a much better investment.

  1. underground wire 5 Star Review

    Posted by on Oct 25th 2016

    I would highly recommend using to install for the fence - the other wires are too light and thin - stretches and breaks underground causing you to either replace or spend hours looking for a break

  2. nice quality thin wire 4 Star Review

    Posted by on Apr 22nd 2016

    This is a 20 gauge wire same as yellow wire but with better coating for better durability. Very happy with the product but I really wish this was offered in a 18 or 16 gauge.

  3. Very Inpressed. 5 Star Review

    Posted by on Apr 12th 2016

    I am very impressed with the strength and function of this wire. We pulled 2000 feet, 4 spools...and connected them (filling connectors with silicon to keep rain out). Fence works great!

  4. More durable than Standard wire 4 Star Review

    Posted by on Apr 9th 2015

    The coating on this wire is far more substantial than the Standard yellow wire provided with the fence kits (both are the same gauge). Not sure why Pet Safe doesn't provide this wire in their kits to ensure longevity of the system. Would have given 5 stars if it was a bright color like the yellow (or maybe red) so you can see it on the ground while you're laying it out.

  7. Good heavy wire 5 Star Review

    Posted by on Jun 4th 2012

    Having dry ground for an expansion to 8 acres, went with the heavier wire to stand up to the very hard ground, it's been standing up great.

  8. High quality heavy duty wire 5 Star Review

    Posted by on Jun 4th 2012

    Not much more to say about the wire. What I was most impressed about was the delivery time. I received this wire two days after ordering and I even used the lowest cost option. Thanks RadioFence.com!

  9. Easy does it! 5 Star Review

    Posted by on May 12th 2012

    It took less than a day to install fifteen hundred feet of this heavy duty wire. The dog learned in four days that she no longer wanted to climb, dig, or chew through a six foot chain link fence. More time was used each week to find the dog than it took to install the fence. Very good solution at an excellent price.

  10. High quality and great pricing! 5 Star Review

    Great quality for the pricing!
