Give your pet more room to roam by increasing the size of your in-ground fence boundary with PetSafe Extra In-Ground Fence Boundary Wire. This roll contains 500ft (152.4 metres) of solid core copper wire that's rated for burial and can cover up to 1/3 of an acre. The amount of wire you need will change based on your chosen layout and the amount of twisted wire.


  • Includes 152.4 metres (500 feet) of wire to expand in-ground fence systems by about 1/3 of an acre
  • Compatible with Innotek, Guardian, or PetSafe in-ground fence systems
  • Rated for burial (solid core 20-gauge copper wire)


  • For best results, use RFA-366 wire connectors and gel-filled splice capsules (sold separately)
  • Waterproof connection required for adding extra boundary wire
