Rated 5 out of 5 by from Industry standard for a reason... Nothing much to say that hasn't been said about these. There is a reason BD is the industry standard...Solid nuts for all-around trad use. Perfect addition to any rack (esp for beginners learning to place pro - start out placing passive pcs and SLCD's will be a cakewalk).

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.

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 4 out of 5 by from Bread and Butter These are good, no nonsense stoppers. Easy to place and retrieve. Really essential gear for thin splitters, building anchors. save your cams for the crux and earn some style points by using stoppers.

Rated 5 out of 5 by from Awesome I recommend these to everybody. The curved shape seems to fit anywhere and they are easy to learn trad with. I often place them and think, "Man, I would love to fall on that piece"

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 4 out of 5 by from great pieces [...] Anyhow, the BD stoppers are very easy to place. They are not as versatile as the DMM wallnuts (in that they don't fit as wide a range of contours), but this is one potential benefit they bear, as good placements in the rock are easier to identify.

Rated 4 out of 5 by from Great first set of Pro Used these to set up a couple of topropes so far, looking forward to doing more with them. The range of nuts seems really versatile for the type of anchors I'm used too, with good overlap between the sizes. I did get one nut really jammed into a crack and it scuffed up the anodization pretty bad, but the structure is still fine and I'm looking forward to scuffing up the rest.

The photo appears to show 2 different color schemes (unless my screen is faulty). Which one is what I will receive?
