This high-tech alternative to traditional fencing is ideal for horses and horse owners alike. Centaur HTP premium 5-inch rails consist of three 12.5-gauge steel wires completely encased in high-tensile polymer. They're safer for animals because they withstand an impact and bounce right back to their original shape, so the chance for animal injuries and costly repairs is reduced. Centaur is engineered to withstand an impact of up to 4,050 pounds per rail! Because it won't splinter, fade, peel, crack or rust, it's virtually maintenance-free. Whether you choose white or black, it keeps its beautiful appearance for years. Centaur has a 20-year limited warranty.
