Petsafe In-ground Electric Fence 20 Gauge Solid Core Wire - 500 feet

This is wire only

If you need flags see the RFA500 kit. 

Need to replace old wire? Need to add on to an existing system? Use our 20 gauge direct burial wire. Remember if you are ordering multiple rolls, you will need splice connectors to connect the rolls together

Use this guide to determine how much wire you need to enclose your yard. This would be an approximation of the amount of wire needed based on typical layouts. You will need more wire if you're doing interior loops to boundary off gardens, swimming pools or other protected areas.

For larger areas, use the following formula: Multiply the total acreage by 43,560- i.e. 10 acres x 43,560 = 435,600

Find the square root of the above number - square root of 435,600 = 660 (this is the length of each side of a 10 acre area that is square in shape. Even if your area is not square, if you multiply this number by four, this is the approximate length of the four sides of a 10 acre area.)

Therefore, one would need approximately 2,640 feet of wire to enclose the perimeter of a 10 acre area. You will need additional wire to run from the transmitter to the perimeter and/or for any interior loops, etc.
