C.A.M.P. Ball NUT N.5

"Discover the essential protection devices for demanding climbing tours: The Ball NUT N.5 from C.A.M.P. These revolutionary belay devices were developed by Steve Byrne in 1987 and are known as the ultimate secret weapon for climbers who prefer self-locking routes. Originally known as Lowe Balls, these little technical marvels provide a reliable solution for the narrowest and most parallel cracks where traditional belay methods would fail."
"The Ball Nuts are particularly effective in pin scars, i.e. cracks caused by repeated hooking and unclipping, as well as in small concavities where even the most modern microcams reach their limits. This lightweight and compact piece of equipment should be in every experienced climber's backpack, especially on classic climbing tours where weight and reliability are crucial. The versatility and precision of the Ball NUT N.5 makes it the ideal companion for anyone who wants to face the challenges of nature with confidence"
