Abstract: A barrier is formed from a framework of posts and rails. Infill sections cover openings in the framework. Post brackets connect posts to rails. Each post bracket includes a collar and an attached holder. The collar is positioned over a post and lowered to a level where a rail is to be attached. The rail is secured within the holder. The holder and the collar are relatively rotatable. Adjacent rails in the barrier are interconnected end-to-end by adapters plugged into the hollow end of each rail. The adapters overlap, and are pinned together, permitting relative rotation between rails. Relative rotation of components permits barrier slope adjustment. Exposed vertical lateral edges of infill sections are covered by an elongate edge protection band having a central ridge and a pair of side recesses. An exposed edge portion of an infill section is received within the recess and clamped against the framework.

Abstract: A barrier is formed from one or more intermediate posts situated between a pair of end posts. Long flexible cables interconnect the end posts and extend adjacent each intermediate post. Each cable is wrapped one or more times around each post. End posts may include dual columns that permit cable windings around both columns. A spike embedded within the end of each cable enhances the purchase that can be gained by a clamp that presses the cable against the end post. The clamp has contact elements with converging side walls that grip the cable near the spike. To maintain the spike in place, a wire rope clip grips the cable over a constriction in its contained spike. Each cable is enclosed by a cable cover extending between adjacent posts. The cable cover is suspended at each post by a pair of tiltable hangers.

Abstract: A barrier framework is formed from vertical posts and horizontal rails. Infill sections cover major openings in the barrier framework. Elongate junction elements overlay each rail and join adjacent infill sections. Edges of the infill sections fit within channels formed in the junction elements. Each junction element has an H-shaped cross-sectional profile, with the arms on one side shorter than those on the other. A cover element encloses the shorter arms of each junction element and clamps infill material against the longer arms.

Abstract: Structural components of a barrier, including posts, rails and pickets, are formed from a conductive substrate that is encased in a corrosion-resistant nonconductive coating. These structural components are assembled by aligning fastener openings in a pair of components, and joining the paired components with a conductive bolt. The shank of the bolt has an enlarged section of peripheral longitudinal ridges that forms an interference fit within each of the aligned fastener openings. Forming this interference fit abrades away the nonconductive coating within the openings, and allows the shank to form a conductive link between the joined structural components.
