The Black Diamond Rocklock Carabiner is the ideal workhorse carabiner for everything. From belaying at the gym to buliding trad anchors, this is the biner for the job. The Rocklock's all round versaility is due to several thoughtful design characteristics. It is Black Diamond's largest Carabiner, yet its shape allows easy use with one hand and the curved spine maximizes the gate opening range, whilst the squared bottom end holds a belay loop or anchor point securely in place to prevent reduce rist of cross loading. The keylock nose increases strength and prevents snagging. It's light enough to compete with the more expensive models but its affordabilty makes it one of our top sellers. This Screwgate version is the most affordable, but also the hardest wearing over repeated use.
BD's largest locking carabiner, the Black Diamond RockLock is perfect for belaying, rappelling or anchors. These carabiners feature minor cosmetic flaws that in no way affect the use or safety of the carabiner, typically the anodization is a little off color.

HOT FORGING VS. COLD FORGING
We use two different forging methods to build carabiners—hot and cold forging. Each has its benefits and using both allows us to achieve the best possible shape, size and strength for each carabiner’s intended use. HOT FORGING, a process where both the rod stock and forge dies are heated, allows us to “move” the metal, creating more intricate shapes, such as our GridLock and Oz biners.
infallible productBy: max hopwood on 24 January 2017this piece of equipment is doubly satisfying. it is both functionally sound and versatile while at the same time being aesthetically impeccable. i will continue my allegiance with both black diamond and wall toys.
