The Perfect Nut

  • Familiarity: I've put it through the wringer

There's nothing to be said about these that hasn't already been said; they're pretty much perfect. Who needs cams if you have a set of these??

The only issue I've ever had is that I once broke the plastic part of a #7 after a pretty big whipper. The nut would probably still work fine bit I decided to retire it after that.

Strong, Durable, Reliable

  • Familiarity: I've used it several times

I've been caring a small rack of these with me over the last couple weeks in France. They're reasonably light, so having 5 or 6 on a biner in your pack or on your harness is no effort. With a few various sizes, you're all set to rig up your improvised belay or protect yourself when needed. These, plus some tatt and a few pitons in your pack are a must for ski mountaineers traveling around in mixed terrain. I find these guys can take a serious beating and I have even rapped off a #3 + #1 equalized. The wires are a bit thin, but strong and durable.

Amazing Stopper

  • Familiarity: I've used it several times

These stoppers are so great! I had to get a new one because my other one was stuck too good in a crack up in Little Cottonwood Canyon (its free game if anyone wants/finds it. ;) ) I spent quite a bit of time trying to dig it out until I took a moment to realize that since it was so stuck, it would have protected me no matter what if I whipped! Great piece of gear.

Great nut

  • Familiarity: I've used it several times

These are my first set of nuts. I got the whole set 1-13. I've used a every single nut in the set and have even had to bail off a couple number 1 nuts. They are strong and will hold. I recommend using a number 3 as a last nut to fall on. The number 2 and 1 are meant only for body weight as the wire is so thin.
The nuts fit really well in the rock but seem to take a beating. A couple have some deep scars from just placing the nut itself.

amazing

    I really recommend this stoppers , very useful and very light .

    love deez nuts

    BD stoppers are a must have in your collection of gear if you have any intentions of climbing trad. They are colorful which helps keep them organized on your rack. The simplicity of a piece of pro such as a nut is what makes them so cool. Double up on these bad boys and you wont regret it because it's easy to place a lot of them.

    Must Have.

    • Familiarity: I've put it through the wringer

    These are a must have for setting top anchors in New England, and they (a full set) have been just right in the situations that call for them. I'm glad I have them!

    These stoppers are legit! I had to buy a new #8 after I blew a piece, fell past my belayer, and welding this bad boy in there. No better mid size stoppers out there.

    Complete!

      Quality product and the last size to complete my full nut set!

      Putting the new #5 to use

      • Familiarity: I've put it through the wringer

      Well some how my crucial #5 fell off my set without me knowing it. Though I could use double sets in these smaller sizes I'm not ready to break the bank. Until then its great to have a nice shiny new stopper!

      • Familiarity: I've used it once or twice and have initial impressions

      Just got #6 and 8 for christmas and already know im going to love them. Already on my rack. Very solid feeling, wire is heavier too.

      double em up

      • Familiarity: I've put it through the wringer

      glad bd lets you buy individuals, as sometimes they stick in cracks too well or you value life too much to rappel off a chockstone. Not much different from other options though I like the HBs a bit better, but haven't had recalls like Wild Country either.

      Number 9

      The number 9 seems to always find it's way into cracks

      Awesome

        These are just classic. Every rack should have a set of stoppers and I would argue that every rack should have these. These were my first pieces of trad pro. Go with these!!
