The Black Diamond Stopper is a superb wire that has a proven track record dating from the days of Chouniard Equipment who developed them in 1972. Stoppers have been shaped to give optimum options for placement in various shaped cracks. The transverse taper permits sideways placements, particularly handy for flared or shallow cracks. The galvanised steel cable is more flexible than wires on other rocks, ensuring the Stopper is less likely to become shaken out as you climb.

Each Stopper is colour anodised by size, this really does help identify the Stopper you require quickly. Stoppers are individually tested prior to leaving the factory so you know they will do their job.

To find the equivalent sized Rock to a BD Stopper just take off 3. So a BD Stopper 9 is the same size as a Rock 6.

Black Diamond Stopper Features

  • Transverse taper is versatile in flares, constrictions and parallel cracks

3 out of 53 out of 53 out of 53 out of 53 out of 5 Black Diamond Stopper Review

Reviewer: Laura Kennedy, Sunnybrow   (13-9-2011)

Pretty much the same as what others before me have said - they are a good first set of nuts but just don’t cam up very well due to the shallow angle on the faces of the nuts.

They are ideal for learning the basics on good holey rock but once you’re pushing your grades you'll likely lack confidence in these.

Up side is they are cheap, cheerful and come in a range of colours - downside is that they don’t cam brilliantly and the colours rub off very quickly!

Reviewer: Jan Stephens, Port Talbot   (13-10-2010)

Purchased as my first set of nuts. The sizes are really wide ranging and cover pretty much everything a beginner could encounter. The smaller sizes ensure that you don’t need to buy a set of micro wires or whatever for thinner cracks, but multiples of the smaller sizes (1/2/3) is probably a good idea when you start tackling smaller cracks. They are a flatter shape compared to others such as WC Rocks, but to my mind this is a bonus. The wire is stiff however on the larger sizes it can sometimes be hard to place at a stretch.

The price is great and overall these nuts are a great place to start.


2 out of 52 out of 52 out of 52 out of 52 out of 5 Black Diamond Stopper Review

Reviewer: Ben, Newcastle Upon Tyne   (30-5-2010)

Have a few different sizes. Through they are slightly cheaper than Wild Country Rocks they are not as good.

The subtle difference in the extremity of concave and convex element of the design seem to account for this. Rocks have a much greater angle than the Stoppers. As a result Stoppers do not seem to place as neatly in many cracks as the Wild Country Rocks. I tend to carry them to complement some of the commonly used sizes of my Wild Country Rocks but always use the Rocks before the Stoppers!

Having said that, they do work fine in most situations.

Facewest comment: There are pros and cons with all rock climbing protection between various manufactures, not least of all between Rocks and Stoppers. Stoppers do tend to be noticeably ‘flatter’ in the smaller sizes, however there are times when this is what the climber may require, likewise smaller Rocks having a greater curve may fit a placement better. However when it comes to the smaller wires please consider looking at Black Diamond Micro Stoppers, as these will compliment any rack and are shaped differently again

Reviewer: mark christie, sunderland   (4-12-2009)

I bought the "standard set", I do like chunky wire on nuts, some sets have very thin wire on the smaller sizes, and the colours are great. They're a good shape, do the job well and feel sercure. However, unless you have some small hexes and small nuts - it may be wise to but the pro set.
