Use Only Burial Approved Boundary Wire

Keep in mind that the wire you use is Important. Burial Approved works better. Use only long lasting waterproof Polyurethane Coated wire with solid copper core.

Should I Use 18-gauge or 20-gauge wire?

Containment system manufacturers designed their systems to be used with 20-gauge wire. We ship all of our containment systems with Premium, Heavy-duty, 20 Gauge Wire. If you want an additional 500ft. of 18-Gauge with your system, we offer a WIREUPGRADE option, which can be purchased with any containment system. Please see below to determine the proper gauge of wire for your use. Remember, 18 gauge wire cannot be purchased from your local pet store or pet supply catalog.

Use 20-Gauge if:
» You have smooth, loose soil or clay
» You are laying your wire next to a fence
» Your yard has few trees or vegetation.

Use 18-Gauge if:
» Rocky soil
» You are installing your wire above ground
» Your yard has many trees
