XL Animal Barrier (Set of 15)

Ground penetrating fence units that are easy to install and humane. They can anchor the bottom of a chain-link fence, fill gaps between the bottom of a chain-link or privacy fence and create an underground fence barrier that dogs cannot dig under.
Features
1.5″ Spacing of tines with two top rails to prevent big dogs from digging out
Can be used in front of a wooden fence
The space between each pole is 1.5″ from the center of the spike to the center of the spike vertically, so the gaps are slightly less than that.
