Moses Enterprises Circle Head Copper

Circle Heads are designed for pasting into horizontal cracks. The circular cable distributes the load equally on either side of the placement.

Copper Heads are harder to bash into a seam but give greater holding power than Aluminium Heads. They therefore tend to be used in shallower more tenuous placements.

Copper Heads and Aluminium Heads (otherwise known as Mashies) are extreme big wall equipment designed for direct aid where the only method of progress is to bash them into dimples and depressions in the rock and hope that they hold when you put your full weight on them. Naturally they are not CE (or any other sort of) tested and are most definitely not to be used for normal trad climbing!
