The Carvex are the technical evolution of the original camming nut, the Hexentric.
The new nut profile with concave and convex faces improves stability in the four different positions of use. Lightweight, cheap and versatile for crag or alpine routes, summer and winter. Unlike a SLCD they don't get full of ice or grit and jam up. Ready slung on Dyneema webbing. Anodized in different colours for easy identification.
