The oval shape reduces carabiner shift and allows the rope to run smoothly. However, there are only a few applications where they excel over other biners. There are many new, small, and lightweight biners that get the job done and greatly lower the weight and bulk of the rack. If you are looking for a big comfy oval, we recommend the Black Diamond Oval Wire because of its price and lower weight. However, for most applications, we would lean toward a lightweight wire gate biner like the Black Diamond Oz Carabiner or even the Wild Country Helium Carabiner.
Black Diamond recalled the Oval carabiner 210076 in February of 2016; this recall concerns carabiners/quickdraws with manufacturing codes between 4350 and 6018. To learn more about this safety recall, head here.
