Great idea... never use them though.
None of my climbing partners will use these, and to be honest — I've only ever placed them out of curiosity. Because of the specific width — you are limited to finding cracks with that exact proportion for the camming-ball to fit. Realistically, any other nut will do. The wires get bent very easily, so the ball twists and turns.


  • It's a working nut


  • Hard to place
  • No one likes them
  • The wire bends easily
  • Why bother?

Great idea... never use them though.

They still hang on my harness, though I often discard them when selecting gear — they're just too limiting.

These are the only gear (apart from pitons) that will go into ultra thin cracks ie smaller than a black alien.

Here's what other sites are saying:

The Ball Nuts from C.A.M.P. are the smallest active protection in the world! Great for rock climbing and aid climbing; these Ball Nuts are color-coded for fast, easy identification.Invented in 1987 by John Middendorf and originally brought to market as Lowe Balls, these have become the secret weapon of many aid and trad climbers. These little wonders will work in small parallel-sided cracks where the only other option is pounding a piton. Ball Nuts also work in pin scars and small flares where cams simply wont fit.


Instead of pounding in a piton try placing a quick and easy C.A.M.P. USA Ball Nut stopper to protect a small fissure while aid climbing.


CAMP USA Ball Nuts are the only choice for hammerless aid-climbing protection in thin, parallel-sided cracks. When the going gets thin, pull the trigger and place a Ball Nut in a crack as narrow as 3mm. Release the trigger, and opposing forces of the brass ball and aluminum nut holds these tiny pieces of protection in place. Much faster and easier on the rock than banging in a knife blade, CAMP Ball Nuts are the last word in protecting thin free climbs and saving time on aid-climbing lines.
