Stay-Tuff fencing is made with a one-piece vertical stay wire. Conventional hinge-joint fencing or field fence uses multiple short wires for stays, allowing the stays to slide, fold down, or even unwind. Stay-Tuff's solid vertical stay provides superior strength, enabling the fence to stand upright on its own. The solid stay provides greater resistance to pressure from stock. With stays available in 3", 6", and 12" spacing, you can select the right fence for your needs.
