Black Diamond Big Wall & Protection Cliffhanger Hook BD5202200000ALL1.
Use the Black Diamond Cliffhanger hook on small to medium edges.
This is the original hook from the Golden Age of climbing. The shape of the hook with its chiseled point and flat tip is a time tested, proven design, making the Cliffhanger a standard hook hanging from today's aid climber's rack. Its bipod base prevents rotation and enhances stability.
