C.A.M.P. Ball NUT N.2

"The Ball NUT N.2 from C.A.M.P. are the perfect protection devices for the most challenging rock cracks that would otherwise be difficult to secureu00e4ren. Originally developed by Steve Byrne in 1987 and known as Lowe Balls, these innovative belay devices have established themselves as an indispensable secret weapon for climbers who prefer self-protecting routes. They are specially designed to find a foothold in narrow, parallel rock cracks where conventional belaying methods might fail."
"The ball nuts are particularly useful in so-called "pin scars" u2013 cracks caused by repeated hooking and unclipping u2013 as well as in small concavities where even the most modern microcams cannot find a footholdu2013. Their extreme lightness makes them an indispensable companion for experienced climbers on classic climbing tours. A set of Ball Nuts, for example in sizes 2 and 3, should be part of every climber's equipment to safely master even the most challenging routes."
