Please Select Wire Gauge

wire-gauge-chart2.jpgThis is a 500 foot roll of Heavy Duty - Solid Core Pet Fence Wire & Flag Kit 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.

Worked well
The 20 gauge wire we just bought worked well, though I do prefer the heavier 18 gauge wire that came with our original order. Even the flags are smaller, less sturdy, less visible, and not as long-lasting. Sorry to see the product quality being reduced.

Heavy Duty
I bought the 14 gauge wire for installation of my dog fence after seeing the wimpy 20ga that the kit came with. I have little doubt that this stuff will last forever. Shipped it quick, price was great.

Works as advertised!
No problems so far. Quick delivery. Not that it really mattered, but I was expecting a 1000 ft spool rather than 2 500ft spools. The fewer the splices the better.
