Where to Buy
Here's what other sites are saying:
Trango reached into an old-school climber's closet to give you the highly versatile and inexpensive Ballnutz. These sliding ball-and-ramp pieces lie between active and passive protections, and they fit in places that cams and stoppers can't, like parallel cracks and thin fissures. With more placement options than a nut and a smaller price tag than any spring-loaded camming device, you simply can't go wrong with the Ballnutz.
