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)

Stoppers are great for people looking to get a set of nuts without spending too much money. If you are hard on your nuts, note that Stoppers have incredible durability. Stoppers clean nicely and offer decent but not fantastic placement versatility. They excel in parallel and bottleneck placements and are rather average in flairs and funky pods.

The UIAA equipment standard provides a baseline for equipment performance in a test lab under controlled conditions on new equipment. Although these test conditions are relevant to the conditions encountered climbing, conditions encountered at the crags and the condition of the equipment are equally important. This recommendation from the UIAA member federation The British Mountaineering Council (BMC) provides vital equipment information that is NOT explicitly addressed in the standard, particularly failure modes of the equipment and recommendations for the use, inspection, maintenance, and retirement of equipment.
