ABSTRACT:
A fence construction for maintaining stock in a confined area made from rust resistant metal tubing and constructed without the use of nuts, bolts, or welding. The horizontal rails are hollow tubing connected at their ends with connectors to form continuous rails and the supporting posts are also formed from tubing with rail supporting hollows or indents formed therein to securely support said horizontal rails. Metal bands placed around the posts just below the rails lock the rails into position and the foot of each post is set in concrete. An additional feature is that one or more of the horizontal hollow horizontal rails may be provided with sprinkler heads and the rails hooked to a source of water under pressure for irrigation of the area the fence encloses.
