The CenFlex 5" Rail Horse Fencing is the more cost effective of the two premier non-conductive horse fencing rails that Centaur offers. It provides the same top-of-industry technology that makes Centaur one of horse fencing's most innovative companies. The CenFlex rail features Centaur's signature polymer coating, so it will never split or rot, providing a huge advantage in protecting the animals from accident. The flexing technology draws from the full strength of the rail, making it able to support up to 4,000 pounds of pressure at any given point. Essentially, a horse running at this fence, even at full speed, would harmlessly bounce off, maintaining the health of the horse and preventing huge losses.

Centaur HTP 5"
vs. This Product

Difference #1: Cenflex is our most economical 5" rail.  It comes with a 20 year warranty as opposed to HTP's warranty of 30 years.

Difference #2: Cenflex is several millimeters thinner than the HTP.

Difference #3: A Cenflex uses the 1-piece vs. 2-piece bracket. Centaur HTP 5" standard brackets are constructed in 2 pieces to lift them off of the posts and prevent wear over time.

Reviews From Cenflex Customers

Low Maintenance Fencing Saves Time

"The best fence product I’ve ever seen. We have a small farm and a good portion of my time has always been spent maintaining fences. Not anymore.”

Edgewood, NM

12 Miles of Fencing, 6 Hours of Maintenance = One Happy Fence Owner

"We installed 12 miles of Centaur Fencing on our new farm in Saratoga-County, New York, in the spring of 1987, and have spent less than six hours in the past 18 months on maintenance. However, its greatest asset to our operation is the safety factor. Horses just do not get hurt when they come into contact with this fence.”
