When the going gets thin, pull the trigger and place a Ball Nut in a crack as narrow as 3mm.

Much faster and easier on the rock than banging in a knifeblade, CAMP Ball Nuts are the last word in protecting thin free climbs and saving time on aide lines.
Bottom Line: CAMP USA Ball Nuts provide ultra-thin crack protection without resorting to the hammer.
