Black Diamond GridLock Screwgate Carabiner

So is the added safety worth it? Just as there’s never a good reason not to wear a helmet, there may be no good reason to avoid the GridLock. Although cross-loading is rarely a concern, the consequences of a failed carabiner are potentially catastrophic. And for climbers concerned with that possibility, the GridLock absolutely achieves what it sets out to do.

Personally, I think that other carabiners, like the Positron, are more multifunctional and therefore more practical than the GridLock, particularly for the price. But for dedicated belaying or beginners, the GridLock is worth a look.
