Black Diamond Camalot C4 0.4 clamping device

For all the top male and female athletes in trad climbing, the Black Diamond Camalot Z4 0.4 made a dream dreamed together come true - a Camalot with a center web that remains rigid during placement and then goes into a "flex mode". Black Diamond made it happen - the patent-pending RigidFlex center stay. The independently routed tension wires ensure that the Camalot Z4 remains completely rigid while under tension and the clamping segments are folded in. After placement, the center web can move, thus preventing migration when rope tension is applied to it. The center web on the larger Camalots features a double-twisted cable design that allows for consistent flex in all directions. The single cable design on the smaller cams avoids kinking when the pull lever is heavily loaded and reduces overall size. With four sandblasted clamp segments for even better holding power, the Z4s are not only an improvement, but also available in even smaller sizes - A valuable addition to your gear!
