DuraWire - Solid Copper Core 500 Foot Spool of 14 Gauge Wire with .045" Insulation - Heavy Duty Insulated Underground Boundary Wire for Electronic Pet Fence System

Wish I would have layed this in the first place instead of the flimsy 20 gauge wire that came with the fence which I had to repair multiple times in just one year until my dog finally found a weak spot and ran off. There is not really a comparison between those two, apples and oranges...!?

Best quality solid copper tree roots don’t like copper you wii not need to replace it I have replaced my 20 gage 3 times in 5years
