Our original aid climbing biner and a reliable workhorse, the Oval is an essential part of any big wall rack.
The iconic, symmetrical Black Diamond Oval is the proven biner for big walling due to its smooth, uniform shape that reduces carabiner shift.
- Uniform shape prevents shifting
- Large carrying capacity
- Proven symmetrical design
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.
