ABSTRACT:
An improved anchoring system for use with regard to a wide variety of materials including an improved anchor head which is very easily and quickly turned over and oriented within the material in which it is embedded. The anchor head is comprised of a triangular or wedge-shaped plate having a deformed central area extending from the front driving point to the rear edge. At least a portion of the rear part of the anchor head is provided with an angular bend forming wings or flaps which provide the improved turnover capability. The system also comprises a self-tightening bracket, an anchoring cable and a drive rod for embedding the anchor head.
