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.
