Defiant Security Fence by BASTEEL Perimeter Systems offers the traditional shadow-box design of the Cambridge style with added features for additional security benefits. These features include additional horizontal rails for strength, tamper-proof security fasteners with a pull-out strength of more than 5,500N, and an optional R-Top curved pressed-point picket attachment for superior security capabilities.
The Defiant Security Fence shadow-box design is depicted by the alternating pickets which promotes air flow. This is a key feature where air circulation is important and climates can be intense. This fact validated by BASTEEL's record at withstanding hurricane force winds. The ingeniously simple design places the rails inside the pickets, allowing the fence to rack to nearly any landscape contour, a staggering six feet of elevation change in just over five linear feet.
