This amazingly light, simple and elegant design arose from a neat application of lateral thinking. Rockcentrics combine the classic "hex" shape with the concave and convex curvatures which are so effective in Rocks. Strength from the triangulation of forces is coupled with highly stable placements and exceptional versatility.

Beautifully made from thin wall extrusions exceptionally durable, lightweight HE30 alloy, each Rockcentric is numbered clearly on the largest surface and equipped with a color-coded Dyneema sling. Rockcentrics have been highly praised, since their introduction in 1998, for versatility, speed of placement, and their light weight.
