ABSTRACT:
An improved climbing anchor utilizing multiple cam elements in which each cam element is independently spring biased by a flat spiral spring located within a recess in the cam element and acting between the pivot mounting and the cam element. The construction provides a more compact camming head assembly, a stronger climbing anchor, more positive action of the spring biasing means and an improved visual appearance.
