Stoppers No. 4-13 racked on an OvalWire carabiner. Black Diamond Stoppers are an essential for every trad rack, designed with a transverse taper that permits sideways placements in flares and shallow seams. Anodized by size, they're quickly identifiable and rounded edges make for easy removal. Each Stopper is equipped with a durable, galvanized steel cable.

  • Durable aluminum heads and steel cables
  • Transverse taper is versatile in flares, constrictions and parallel cracks
  • Rounded edges for easy cleaning (smaller sizes are straight for better surface contact)

Rated 5 out of 5 by from Tried and True Stoppers, nuts, chockstones, how can you go wrong with a solid set of passive pro? Chouinard, and now BD, has been producing these things since 1972 and while the basic premise remains the same, minor tweaks and improvements keep making them better. Color coding has been around for awhile and the latest version has the size of each stopper labeled on the wire tag, rather than on the nut itself (where it is quickly worn off). Not that I ever search by number, but it is nice and easy to see which nuts may have gone missing or need replacement after an epic adventure where one or two may have been swallowed....

Rated 5 out of 5 by from What you'd expect Great nuts. Seem to ride that balance well between being too soft that they get cut up too easily like brass and not placing as well. A nut is a nut. The wires are stiff, which is a plus. Bought doubles 7-3.

Rated 4 out of 5 by from The Standard This is THE standard set of nuts. Building a new trad rack? This set 4-13 is probably what you want. There are some other nuts out there that may be better at some things(and pricier), but this is the set they're compared to. Also this one comes with a carabiner! yeah!!

Rated 5 out of 5 by from Tried-and-True These are great stoppers, take a look around and you will see them on most trad racks. I would also recommend buying a number 3 it is rated for lead falls and it has been very helpful to have in the Northeast.

Rated 5 out of 5 by from Classic Pro Stoppers are easy to place, the color coding is awesome, and the set of 4-13 gives a pretty solid range. Classic pro and the foundation of a good rack.
