Invisible Fence® Brand pet containment systems use a direct burial single copper wire protected by a thick outer sleeve of insulation to establish the boundaries of your dog's underground fence.
The wire is buried to create a hidden loop antenna that provides the radio signal for the system - and transmits the signal to your dog's Computer Collar® to remind your dog exactly where the fence is!
This 500 Foot Roll of Perimeter Wire is used for longer run applications and to add additional sections to your existing Invisible Fence® Brand system.
Also available in 50, 250, and 750 ft spools of Invisible Fence® Brand Replacement Perimeter Wire. If you are repairing or extending your electronic dog fence, it is helpful to use the Wire Repair Splice Kit.
If you need help in repairing or extending your Invisible Fence® Brand pet containment system, please schedule a service call.
