Copperhead (climbing)

Copperheads consist of a three to six millimeters thick copper cylinder which is pressed by a steel cable sling around. The copper cylinder is usually taken with a hammer into small rock cracks, with the copper of the shape of the crack adapts and becomes stuck there. Copperheads belong to the group of malleable hardware, the (English ) Bashies. A sharp chisel and a hammer is best used to hammering of Copperheads.

Unlike Rocks or Hexentrics Copperheads are intended for very small rock cracks where other clamping devices or wedges no longer fit into it. The holding forces of Copperheads are difficult to predict and generally low. You should therefore find no real use as an intermediate backup and only as a last option for application.
