Hands-on Gear Review
Cons: Heavy, bulky, gate gets hung up
Manufacturer: Black Diamond
The Black Diamond Oval is the classic carabiner design and Black Diamond has been making them for as long as anyone. The oval design is tried and true and it's just kinda cool to have a few of these old school carabiners lying around. However, there are only a few applications where they excel over other biners. There are many new, small, and lightweight products that get the job done and greatly lower the weight and bulk of the rack. The oval shape reduces carabiner shift and allows the rope to run smoothly. The Black Diamond Oval Wire is a lighter alternative. Overall, we like to keep a few ovals around, but generally use lighter biners for most applications. If on the other hand, you like the beefy solid gate design, consider the Petzl Djinn Straight Gate, which is lighter than the Oval, but stronger and still very easy to handle.

OutdoorGearLab Editors' Hands-on Review
The Black Diamond Oval carabiner scored highly in rope pull smoothness; when you run a rope though them there is less friction than with almost any other non-locking carabiner. This makes them excel for top rope anchors where two of them are used "opposite and opposed." They are also great if you are setting up a carabiner brake rappel (however, that type of rappel is used less and less considering there are other ways to get yourself down if you drop your belay device). Ovals are good for racking slings and pitons because the gear can slide around easily. Some aid climbers like them for their aiders and daisy chains because they are just bigger and easier to handle; they also don't cause "biner shift." That said, we have never found biner shift to be a big issue.
The solid gate Black Diamond Oval is incredibly heavy and bulky; over twice the weight of many wiregate biners. If you have a big trad rack or big wall rack, that weight adds up fast. While they are good for racking pitons and slings, nuts get hung up easily on the unexposed notch, especially if there are a lot of nuts. The Black Diamond Oval is the heaviest we tested at 64g, yet the weakest at only 18kn closed gate strength.
Ovals are great for top roping or any situation where smooth rope pull is needed. It's not a bad idea to buy four to six of them when you first start climbing because they are cheap and you can learn the old school "carabiner brake rappel."
This is one of the cheaper biners out there. That said, considering its limited applications, we would rather buy a cheaper wiregate biner if we were on a tight budget.
