These fence kits don't include a rodent barrier and don't overlap on the ground. That means for example if you order a 6 foot fence kit, we will ship you posts that come out of the ground 6 feet and 6 tall animal fencing to be hung on those posts. This configuration is great for customers blocking off shrubs or other plants, for example, from animals. It's also a great choice for customers that need to take down their fence seasonally or for a removable animal fence (grazing). Our post sleeve system includes locking set screws which hold our animal fence posts in the ground. Ground sleeves stay in the ground, while posts and fencing are removed for storage.
