Description

Time-tested passive pro, Stoppers are a direct link to the original chocks that started the clean climbing revolution. 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)
  • *Sizes 1 and 2 are for direct aid only

Stoppers is rated 5.0 out of 5 by 8.
Rated 5 out of 5 by from A must for any rack These stoppers (nuts) are a staple for any climber's rack. The shape gives you several different orientations for placement so it covers a wider range of widths. The transverse taper makes them easy to place and really secure. I have yet to have one pop on me in a fall. They can be a bugger to remove so bring a nut tool. I've never used sizes 1 & 2 since I don't do any direct aid climbing, but I'm sure they work just as well as the rest.

Rated 5 out of 5 by from Call me old fashioned but these nuts are the best Call me old fashioned but these nuts are the best. BD nuts are the mainstay stopper in a climber's rack. There are very few constriction cracks where these don't work. Although they are not "off-set", they have a trapezoidal shape that allows them to be on placed their horizontal securely in mildly off-set cracks.

Rated 5 out of 5 by from Mandatory Part of Your Trad Rack (and Your Friends' Too) BD and, before BD, Chouinard, has made what i think are the best stoppers since, well, since good stoppers have been made. Get a full set and you'll be the envy of your Trad partners. Talk 2 of them into buying the same full set and you'll be ready to climb the Tower together ;-)

Rated 5 out of 5 by from Best stoppers out there These stoppers are easy to place and easy to clean. Love the shape and they seem to take abuse better than other brands. A absolute essential for every rack.

Rated 5 out of 5 by from Best nuts around I've been using BD nuts all my life and love them to bits. They are simple, reliable and affordable and they work in every sized crack you can imagine.
