To secure your fence, keep pets in, and predators out:
On chain link fences, place the spikes over the bottom wire of your fence. Stop driving when the top lateral wire is even with bottom of fence.
On a wooden privacy fence, install from inside of fence (same side of post) or outside of fence, driving unit straight down. Stop driving when the top lateral wire is even with the bottom of the fence. If wood is being chewed, install from inside of fence straight into ground and attach top lateral wire with a staple.
For best results, use a hammer and gloves while hitting each spike evenly. If one or more spikes comes in contact with a rock, remove spike or bend it out of the way. If the ground is too hard for initial installation, try saturating with water or installing after rainfall.
