These are specially designed fence kits that include protection against climbing animals (keeps animals in, keeps animals out or keeps animals both ways in and out) when other types of fences have not worked. The posts in these kits include extensions on the top of each post; when paired with included fencing, these extensions make an overhead canopy that deter animals from climbing over. These kits can also be configured with overlap on the ground and also a rodent barrier. They are most often used by customers that want better protection from climbing animals like raccoons, but are not concerned with top protection (birds).
